Ported from the private repo via bin/publish.sh, plus a manual catch-up on files that had drifted out of sync before today: - launch_nexus.ps1: health-check based restart decisions instead of a bare port-listen check (a wedged leftover process squatting a port used to look "already running" and block the real service from starting), a script-path quoting fix for Start-Process, hidden console via a wscript.exe wrapper (bin/launch_nexus_hidden.vbs), and a taskbar/window icon for the native app window. - Sidebar: slim icon+text nav rows instead of bulky bordered buttons, tighter spacing throughout. - Settings: full-width layout, a Vite dev-server Start/Stop toggle (synapse/frontend_manager.py + /frontend/* endpoints), and the Linux-only Icon Branding section now gated on the new /status `platform` field instead of always rendering. - Chatbot: a Think toggle next to the model picker, so extended thinking can be flipped without leaving the chat page. - management/ncp.py: faster start/stop polling (0.25s steps instead of 1s), Vite no longer blocks `ncp start` on Linux and is skipped outright on Windows. Note: the private repo also has a Mail (IMAP/SMTP) feature; it's intentionally not included here, so the Mail-only pieces of main.py, App.jsx, and requirements-windows.txt were left out of this port.
