Remote Control toggle disabled after resume-from-sleep (works only after full quit+relaunch or new session)

Remote Control (settings.json remoteControlAtStartup: true) activates correctly when a session starts fresh (new session / full app relaunch) — confirmed working via "Continue previous session".

However, when the PC is closed (sleep) and reopened without the app fully quitting, Remote Control is disabled and the toggle option doesn't appear in the settings panel at all — it only reappears after a full quit+relaunch or starting a brand new session.

Expected: Remote Control should either persist across sleep/wake, or the toggle should remain visible/re-enable automatically without requiring a full app restart.

Repro:

1. Set remoteControlAtStartup: true in ~/.claude/settings.json.
2. Start a session, confirm Remote Control toggle is visible and ON.
3. Close the laptop lid (sleep, app process not fully quit).
4. Reopen — Remote Control toggle no longer appears in the settings panel.
5. Fully quit and relaunch the app, or start a new session — toggle reappears and is ON again.
