Make the runtime event-driven and battery efficient - #3
Conversation
📝 WalkthroughWalkthroughThe change removes Binder, broadcast, provider, wake-activity, and watchdog paths. It adds conditional bubble persistence and service shutdown, updates boot and update scripts, revises status surfaces, and adds release-time power-behavior checks.

Serialize bubble_enabled updates.
RootShell.setBubbleBootEnabled and setBubbleBootEnabledAsync start independent su -c processes. MainActivity and OverlayService can issue enable and disable updates without shared ordering. A disable can complete before an earlier enable, so the earlier enable can recreate bubble_enabled after the final disable. sync_bubble_marker_from_prefs does not order runtime writes, and status.sh reads the marker without calling it.
Route app-side marker writes through one FIFO worker or reject stale writes with a generation value. Add a rapid enable-then-disable regression test that asserts the marker is absent after the final disable.

Validate the process identity before kill.
A stale numeric PID can be reused by an unrelated process. This installer then terminates that process as root. Match /proc/$old_watchdog/cmdline against the watchdog script before kill, as module/scripts/common.sh:66-74 already does.
Proposed fix
- case "$old_watchdog" in ''|*[!0-9]*) ;; *) kill "$old_watchdog" 2>/dev/null || true;; esac
