+Program viewer side panel + writeback API + docs link fix.
+
+### Home Assistant integration
+
+- Lit/TypeScript side panel for the program viewer (Phase C): filterable list, slide-in detail panel, structured-English token rendering, REF-token click-to-filter, live-state badges (SECURE / NOT READY / ON 60% / Away / 72°F) sourced from the coordinator, "Fire now" button calling `omni_pca/programs/fire` over the websocket.
+- Program writeback: `DownloadProgram` wire path, HA write API, Clear / Clone UI in the side panel.
+- esbuild bundle committed at `custom_components/omni_pca/www/panel.js` (~34 KB minified) so end-users don't need Node.
+- `manifest.json`: `documentation` URL points at <https://hai-omni-pro-ii.warehack.ing/> (was the GitHub repo); matches the canonical docs site already referenced from `pyproject.toml`.
