feat(desktop): split daemon and release settings to main process

Move daemon management and release channel settings out of the renderer's
AsyncStorage and into a desktop-owned settings store persisted by the main
process. Adds a "Keep daemon running after quit" option, a daemon lifecycle
section in settings, and a one-time migration of legacy renderer-owned
desktop settings.
