Fix desktop layout and window controls at half-screen width (#1983)

* fix(app): preserve desktop layout in half-screen windows

Treat native window controls as physical corner obstructions instead of deriving clearance from compact layout state. Keep 751px windows in desktop mode while preserving usable content when persisted sidebars are wide.

* fix(app): retain sidebar width across window resizes

* fix(app): yield app sidebar to narrow settings

* test(app): wait for mobile sidebar motion to settle

* fix(app): yield navigation to narrow workspace explorer

* fix(app): mark sidebar sizing helpers as worklets

* fix(app): hide app navigation when space is constrained

 It launches its own Electron-flavored Expo server and passes that URL to Electron.
 Override the CDP port with `PASEO_ELECTRON_REMOTE_DEBUGGING_PORT` when `9223` is busy.

+```bash
+npm run verify:electron-cdp --workspace=@getpaseo/desktop

+The verifier reads the same `EXPO_PORT` and

+testing an isolated instance on non-default ports.

 When running a dedicated Electron QA instance against a non-default Expo port, set
 `EXPO_DEV_URL` explicitly. Desktop main defaults to `http://localhost:8081`, so
 `PASEO_PORT=57928` alone starts Metro on 57928 but Electron still loads 8081.
