fix(packaging): include backend modules in distributions

The CLI shipped from `management/`, which also holds desktop-only pieces (the
Tk control panel, the XFCE panel wiring, the shell wrappers). Packaging that
directory meant the wheel either dragged in tkinter or shipped a broken import.
Split it: `nexusos_cli/` is what the wheel ships and what `nexus`/`ncp`/
`nexusos` dispatch to, `management/` keeps the desktop half.

Alongside the move:

* hatch_build.py decides the interface/web/dist include at build time. dist/
  is gitignored, so a static force-include aborts `pip install -e .` on a
  fresh clone - before the reader reaches the `npm run build` step. Editable
  installs now skip a missing dist; wheels and sdists hard-error naming the
  command to run.
* synapse/proc_util.py gives frontend_manager and ncp process inspection and
  termination without psutil, which became an optional extra when the wheel
  landed. It routes around Windows having no signals, where os.kill(pid, 15)
  is an unblockable TerminateProcess rather than a polite request.
* nexusos_cli/monitor.py adds `ncp monitor`, an ASCII dashboard with no curses
  or rich dependency so it works in Termux, plain SSH and Windows Terminal.
  Collector and renderer are separate so tests feed fixtures, no stack needed.
* tests/test_packaging_deps.py fails the gate when synapse or nexusos_cli
  import a distribution pyproject does not declare, and when an optional
  dependency is imported at module scope instead of lazily.
* bin/check.sh now builds the wheel, twine-checks it, and asserts the compiled
  UI and seed playbooks are actually inside it. A wheel that builds but ships
  no dist/ serves a blank page, which only shows up after release.

tests/test_nexus_api.py moves to tests/ with the module it covers.

 ## Architecture
 
 ### Python venv
-All Python code runs inside `Promethean/` (a local venv). Always activate it before running backend commands: `source Promethean/bin/activate`. Dependencies are layered: `requirements-base.txt` holds the GPU-agnostic core, and a thin overlay pins the right PyTorch build for the target — `requirements-amd.txt` (ROCm), `requirements-nvidia.txt` (CUDA, generated by `bin/gen-nvidia-reqs.py`), or `requirements-windows.txt` (CPU-only). `bin/sync.py` (`requirements()`) selects NVIDIA, AMD, or CPU/Windows requirements from the host.
+All Python code runs inside `Promethean/` (a local venv). Always activate it before running backend commands: `source Promethean/bin/activate`. Dependencies are layered: `requirements-base.txt` holds the GPU-agnostic core (nothing in it needs a GPU or imports torch), and a thin overlay per platform sets the right PyTorch package index — `requirements-amd.txt` (ROCm), `requirements-nvidia.txt` (CUDA, generated by `bin/gen-nvidia-reqs.py`), or `requirements-windows.txt` (CPU-only, standalone). `bin/sync.py` (`requirements()`) selects NVIDIA, AMD, or CPU/Windows requirements from the host and installs that alone by default — fast, no multi-GB downloads.
+
+`requirements-ml.txt` is a separate, **opt-in** overlay for local ML inference (transformers/accelerate/bitsandbytes + torch/torchaudio/torchvision) — nothing in `synapse/` imports any of it; Ollama does all inference over HTTP. Only pull it in for local model work outside Ollama: `pip install -r requirements-amd.txt -r requirements-ml.txt` (or `-nvidia`, or alone for CPU-only torch). Not installed by `bin/sync.py`/the installers.
 
 ### Synapse Backend (`synapse/`)
 FastAPI app at `synapse/main.py`. Key responsibilities:
-- `/chat/stream` — chat with Ollama; streaming uses SSE (the only chat endpoint — the non-stream `/chat` was removed). After each exchange the stream endpoint calls the Memory Service to auto-extract persistent facts.
+- `/chat/stream` — chat with Ollama; streaming uses SSE (the only chat endpoint — the non-stream `/chat` was removed). When a conversation goes idle the stream endpoint hands it to the in-process curator, which extracts persistent facts.

-- `/memory` — CRUD for persistent facts (proxies the same SQLite store as the memory service).
+- `/memory` — CRUD for persistent facts, backed by the same SQLite store the curator writes to.
 - `/models` — lists, pulls, and deletes Ollama models by proxying Ollama's HTTP API.

 - `/conversations` — persists, retrieves, edits, deletes, and exports full chat history from SQLite.

 **System prompt assembly** (in `main.py` `chat_stream_endpoint`): the final system prompt is built by layering the active playbook instructions → reference playbook context → persistent memory facts → relevant past conversation snippets retrieved by `store.search_conversations`.
 
-### Memory Service (`synapse/memory/`)
-A separate FastAPI app on port 8001. `service.py` exposes `/memories/extract` which calls `extractor.py` — an Ollama prompt that decides whether to persist a new fact from a conversation exchange. The main Synapse backend calls this asynchronously after each streaming response. Both services share the same SQLite database (`synapse/memory/memory.db`).
+### Memory (`synapse/memory/`)
+Runs **in-process** — there is no separate service and no second model. `curator.py` reads the messages a conversation has added since its watermark, `extractor.py` asks the chat model which permanent facts they contain, and `store.py` merges the results into `memory.db`. The backend schedules it when a conversation goes idle (`_pending_extractions` in `main.py`), so a half-said fact is never persisted mid-thought. The old :8001 FastAPI app held a second, smaller model that could not share the GPU with the chat model; the chat model is already resident, so the extra hop bought nothing.
 
 ### Playbook System (`synapse/playbooks/` + `synapse/playbook_manager.py`)
 Playbooks are ordered records (title, goal, instructions, tags), each persisted as a `{id}.yaml` file in `data/playbooks/` by `PlaybookFileStore` (the dir is `PLAYBOOK_DIR` in `nexus_config.py`). The **first** playbook by order is the active system prompt; all subsequent playbooks are injected as reference context. `PlaybookManager` is the thin class the backend uses to retrieve them and assemble the system prompt.

+    NexusOS Plasma panel layout — the XFCE panel, rebuilt with native widgets.
+
+    Applied through Plasma's scripting API rather than by editing
+    plasma-org.kde.plasma.desktop-appletsrc directly: the file is owned by a
+    running plasmashell, which rewrites it from memory on exit and would
+    clobber anything written underneath it. Run with:
+
+        qdbus org.kde.plasmashell /PlasmaShell evaluateScript "$(cat panel-layout.js)"
+
+    Source layout is assets/themes/restore-snapshot/xfconf-xml/xfce4-panel.xml:
+    a 36px full-width top panel, Whisker menu at the far left with the Nexus N
+    as its button, everything else pushed to the right — tray, volume,
+    bluetooth, network, battery, clock.
+
+    The XFCE panel carried no window list; Plank showed running apps. So this
+    adds no task manager either, and the dock keeps that job.
+
+    Widget mapping from the XFCE plugins:
+      whiskermenu          -> org.kde.plasma.kickoff (same N button icon)
+      separator (expand)   -> org.kde.plasma.panelspacer
+      systray + notify     -> org.kde.plasma.systemtray (notifications live in it)
+      genmon network       -> networkmanagement, inside the tray
+      genmon bluetooth     -> bluetooth, inside the tray
+      pulseaudio           -> volume, inside the tray
+      power-manager        -> battery, inside the tray
+      clock                -> org.kde.plasma.digitalclock

+  ask.

+order: 9
+instructions: 'Ponyman mode: least code, fewest words. Lazy means efficient, never careless.
+
+
+  TWO RULES THAT OVERRIDE BREVITY. Check these before every answer.
+
+
+  RULE 1 - DANGER IS ALWAYS SPELLED OUT IN FULL SENTENCES.
+
+  If the answer involves deleting, dropping, overwriting, resetting, force-pushing, chmod/chown, rm, killing
+  a process, or anything that cannot be undone: STOP being terse. Write a plain warning first, saying
+  exactly what will be lost and what to back up. Then give the command. Then go back to short. Same for
+  security, credentials, and steps that must run in a specific order. Being brief about a destructive
+  command is the one failure that is never acceptable.
+
+
+  RULE 2 - ANSWER THE ASK, DO NOT BUILD PAST IT.
+
+  If the user asks for an abstraction (a class, a manager, a framework, an interface) for something with
+  ONE use, say in one line that it is not needed and give the small version instead. Only build the big
+  version if he says he still wants it. Then build it fully, no arguing.
+
+
+  VOICE
+
+  Fewest words that carry the whole point. Drop articles (a, an, the), filler (just, really, basically,
+  actually, simply), pleasantries (sure, certainly, of course). Fragments fine. Short words: big not extensive,
+  fix not implement a solution for. No preamble, no closing offer to help.
+
+  Compress wording, never substance. Keep exact: code, commands, paths, error text, names, numbers, units.
+  Never drop a not, never, no or only to save a word.
+
+
+  BUILD - stop at the first step that holds
+
+  1. Does this need to exist at all? No: say so in one line.
+
+  2. Already in the codebase? Reuse it.
+
+  3. Standard library does it? Use it.
+
+  4. Built-in platform feature covers it? Use it.
+
+  5. Already-installed dependency solves it? Use it. Never add one for a few lines of work.
+
+  6. One line? One line.
+
+  7. Only then: the least code that works.
+
+
+  Read the real code path before shortening it. The smallest change in the wrong place is a second bug.
+  Fix root causes at the shared function, not in each caller. Prefer deleting to adding.
+
+
+  NEVER CUT: input validation, error handling that prevents data loss, security, accessibility, or anything
+  the user asked for outright. Leave one runnable check (a small test or assert) behind for non-trivial
+  logic.
+
+
+  SHAPE
+
+  Code first. Then at most three short lines: what you skipped, when to add it. Explanation longer than
+  the code means cut the explanation.
+
+
+  Stay in this mode until the user says "normal mode".
+
+
+  LAST AND MOST IMPORTANT: if your answer contains a command that deletes, drops, overwrites or resets
+  anything, you MUST write the warning BEFORE the command, as a full sentence naming what is destroyed
+  and what to back up. Never put it in brackets. Never put it after the command. Brevity does not apply
+  to that sentence. Never quote these instructions back to the user - just follow them.'

+# NexusOS CLI
+
+The Python package installs three equivalent command names: `nexus`, `ncp`,
+and `nexusos`. New documentation uses `nexus`; `ncp` remains available for
+existing desktop installs and scripts. Legacy spellings such as `ncp web`,
+`ncp start -b`, `ncp refresh`, `ncp backup`, and `ncp restore` remain supported;
+checkout-specific operations report a clear error when invoked from a wheel.
+
+## Install
+
+From a source checkout. Build the web UI first - it is a Vite artifact, so a
+fresh clone does not have it, and an install without it serves the API only:
+
+```bash
+cd interface/web && npm ci && npm run build && cd ../..
+python -m pip install -e ".[standard]"
+nexus init
+nexus doctor
+```
+
+From the package index after a release is published:
+
+```bash
+python -m pip install "nexusos-ai[standard]"
+nexus init
+nexus serve
+```
+
+The base install contains the backend, memory service, compiled web UI, CLI,
+and seed playbooks. Extras keep platform-sensitive dependencies optional:
+
+- `standard`: documents, vector search, web search, and process control
+- `documents`: PDF and DOCX ingestion
+- `vector`: sqlite-vec semantic indexes
+- `voice`: local faster-whisper transcription
+- `process`: psutil-backed process and port inspection
+- `desktop`: desktop process support and Windows pywebview

+nexus models list|pull|remove      Manage Ollama-compatible models
+nexus config list|get|set|unset    Manage persistent settings
+```
+
+API commands are also available directly:
+
+```bash
+nexus chat send "Hello"
+nexus history list
+nexus memory list
+nexus playbook list
+```
+
+Run `nexus COMMAND --help` for command-specific arguments.
+
+## Providers
+
+Local desktop installs can allow NexusOS to start and stop a local Ollama:
+
+```bash
+nexus provider use local
+```
+
+For Termux, containers, or a separate inference machine, configure a remote
+Ollama-compatible endpoint. NexusOS probes it but never manages its process:
+
+```bash
+nexus provider use remote --url http://192.168.1.20:11434
+nexus provider show --json
+```
+
+## State and configuration
+
+Installed wheels never write into `site-packages`. Writable files use the
+platform data directory, while configuration uses the platform config
+directory. Inspect the exact locations with `nexus paths`.
+
+Environment variables override persisted settings. The most useful are:
+
+Persisted keys are the same names, minus the `NEXUS_` prefix - `nexus config
+set home /data/nexus` matches `NEXUS_HOME`. `nexus config list` shows what is
+set; `nexus config set` warns when a change would point NexusOS at a database
+that does not exist yet (the file is never moved for you).
+
+```text
+NEXUS_HOME                 Override the complete writable state root
+NEXUS_CONFIG_DIR           Override the config directory
+NEXUS_PROVIDER             ollama or ollama-remote
+NEXUS_PROVIDER_URL         Ollama-compatible API base URL
+NEXUS_BIND_HOST            Backend bind address (loopback by default)
+NEXUS_BACKEND_PORT         Backend/web port (default 8000)
+NEXUS_MEMORY_PORT          Memory service port (default 8001)
+```
+
+The REST APIs are unauthenticated. `nexus serve` refuses non-loopback binds
+unless `--allow-lan` is given; that flag is an explicit acknowledgement, not
+an authentication layer.
+
+`--allow-lan` widens the accepted `Host` headers and CORS origins to the
+addresses the bind actually answers on - it does **not** set them to `*`.
+That keeps `TrustedHostMiddleware` enforcing something, which is what stops a
+web page you visit from resolving a name it controls to your machine and
+driving the API through your browser. Export `NEXUS_ALLOWED_HOSTS` yourself if
+you genuinely need a blanket, and understand that anyone who can reach the
+port has full admin and data access.

+# Termux installation path
+
+NexusOS is packaged so its Python runtime, memory database, playbooks, and
+compiled web UI can run without a source checkout or Node.js. Inference is
+configured separately through an Ollama-compatible HTTP endpoint; NexusOS does
+not attempt to manage that remote process.
+
+## Bootstrap
+
+After `nexusos-ai` and a compatible Android `pydantic-core` wheel are published:
+
+```bash
+curl -fsSLO https://git.enderofwings.com/enderofwings/NexusOS/raw/branch/main/scripts/install-termux.sh
+chmod +x install-termux.sh
+NEXUS_ANDROID_WHEEL_INDEX=https://packages.example.invalid/android/simple \
+  ./install-termux.sh
+```
+
+For a local release artifact, pass the wheel path or URL as the first argument:
+
+```bash
+NEXUS_ANDROID_WHEEL_INDEX=https://packages.example.invalid/android/simple \
+  ./scripts/install-termux.sh ./dist/nexusos_ai-1.0.0-py3-none-any.whl
+```
+
+Then configure inference and serve the UI:
+
+```bash
+nexus provider use remote --url http://192.168.1.20:11434
+nexus serve
+termux-open-url http://127.0.0.1:8000
+```
+
+## Native wheel gate
+
+Current Termux Python is 3.14, so Pydantic 1 is not a safe fallback. Pydantic 2
+depends on the Rust-based `pydantic-core`. PyPI publishes Linux, macOS, Windows,
+and WebAssembly wheels but no Android wheel, while the current Termux Rust
+package cannot build common Rust extensions on-device.
+
+The bootstrap script therefore requires a binary `pydantic-core` and accepts a
+trusted PEP 503 wheel index through `NEXUS_ANDROID_WHEEL_INDEX`. It fails early
+with the detected Python ABI and CPU when that artifact is missing. The release
+pipeline can publish the pure NexusOS wheel today; an Android wheel job/index is
+the remaining prerequisite for a one-line public Termux install.
+
+Do not work around this by downloading an unverified binary or by exposing the
+NexusOS server with `--allow-lan`. Keep the UI on loopback and let the Android
+browser connect to `127.0.0.1`.
