v1.1.21

Fix: installing a new .ipk over the app (webOS Dev Manager / Homebrew Channel update) left the control service unreachable - the app stayed on 'checking status' until the TV was rebooted. Cause: the service held a permanent keep-alive activity and ran resident; the installer killed that process abruptly and ls-hubd kept advertising the dead PID (a stale 'ghost' bus registration). Now the service idle-exits shortly after the app closes (so nothing resident is killed at install time) and explicitly de-registers its Luna bus handle on every exit path, so ls-hubd frees the name immediately. Updates no longer require a reboot.
