Introduce a minimal operations console reachable on a dedicated UI port (default 8081), kept separate from the OpenAI-compatible API port. - ts_web/ holds the SPA shell (index.html, app.css, vanilla app.js) with sidebar navigation for all views from readme.ui.md and a working Overview page backed by a new /_ui/overview JSON endpoint. - scripts/bundle-ui.ts walks ts_web/ and emits ts_bundled/bundle.ts, a single generated module exporting every asset as base64. Mirrors the @stack.gallery/registry pattern so deno compile binaries embed the entire UI with no external filesystem dependency at runtime. - ts/ui/server.ts (UiServer) serves assets from either the bundled map (default, prod) or directly from ts_web/ on disk (dev). The source is chosen per-config and can be overridden by UI_ASSET_SOURCE=disk|bundle. SPA fallback routes unknown extensionless paths to index.html. - IModelGridConfig.ui block with enabled/port/host/assetSource defaults; config init writes the block, the normalizer fills in defaults on load, and the daemon starts/stops the UI server alongside the API. - deno.json gains a bundle:ui task; compile:all now depends on it so released binaries always contain an up-to-date bundle. dev task sets UI_ASSET_SOURCE=disk for hot edits. - ts_bundled/ is gitignored (generated on build). - test/ui-server.smoke.ts exercises bundle and disk modes end to end (index, app.js, SPA fallback, /_ui/overview, 404).
