Keeps both sides: frontend detection and bot wiring from tickets 02/03, optional
sections from ticket 04. The a-empty-sections eval now uses the shared "fixture" key.

 All updates use one envelope: `{"event": "<name>", "data": {...}}`.
 - **Desktop (PyQt):** Python calls `window.__pyMsg(json)` via `runJavaScript` (see `bridge.py`).
+  `bot_runner.py` turns the bot's output lines into `status`, `step` and `log` events, and keeps every raw line in `bot_raw.log`.
 - **Web:** the page polls `GET {API_BASE}/dashboard` (returns `dashboard_data`) and
   `GET {API_BASE}/run/status` → `{"running": bool, "events": [envelope, ...]}`. Poll fast (2s) only while running.
 - **No bot yet:** with `SAMPLE_DATA = true`, the page answers its own data actions with sample envelopes.
