jonandClaude Opus 4.8 f4aea78b55 feat(rag): overlapping chunker, retrieval knobs, sqlite-vec index 
- Chunker: char overlap across boundaries + hard-split of oversized paragraphs.
- Retrieval knobs: rag_top_k / rag_min_score in settings + Settings UI.
- Vector index: sqlite-vec ANN over document embeddings, dual-written and
  backfilled, with brute-force cosine as the guaranteed fallback.

jonandClaude Opus 4.8 ac0eb1e5f6 feat(rag): PDF/docx ingest + chat citations 
- Upload endpoint (base64 JSON, no multipart dep): extracts text from
  pdf/docx/txt/md via pypdf + python-docx, then runs the existing
  chunk/embed pipeline. Documents page uploads files straight through.
- Citations: the chat stream emits an SSE `sources` event listing the
  documents that fed the answer; the UI shows them as chips under the reply.
- Deps: pypdf, python-docx (both pure-Python, Windows-safe).

jonandClaude Opus 4.8 f509034fdd feat: playbook tools, RAG, vision, voice, chat controls, faster boot 
- Tool-using playbooks: read-only tool registry (search_memory,
  search_history, search_documents, list_models, get_time), per-playbook
  allowlist, agentic loop, and a "running tool" status indicator.
- Document ingest / RAG: documents table + chunker + embed/cosine retrieval
  reusing the existing stack; Documents page (upload/paste, viewer, delete);
  top-k chunks injected into the system prompt.
- Vision chat: attach images, base64 into /api/chat.
- Voice I/O: Web Speech dictation + read-aloud (browser-native, no backend).
- Chat controls: stop, regenerate, edit-and-resend; num_ctx knob in Settings.
- Per-playbook model override.
- History polish: per-conversation + bulk ShareGPT export.
- Faster ncp start: UI up first, Ollama warms in the background, with a
  per-phase timing readout.

jonandClaude Opus 4.8 6755a2477d fix(status): /status blocked the event loop and outran its own client timeout 
The backend logged 200 OK for polls the client had already timed out on.
is_running() waited 2s for an Ollama that ships OFF (now 0.5s), is_available()
spawned 'ollama --version' every call and that command blocks ~5s when Ollama is
wedged (now cached), and both ran synchronously inside an async def, stalling the
event loop on every poll while the UI polls continuously (now to_thread).

Measured with Ollama's port blackholed: /status 5.89s -> 0.64s, concurrent GET /
stalled -> 0.06s. Poll timeout in nexus_window.py raised 2s -> 5s for margin.
