Two real bugs from final review:
- Clear recovery state on window 'closed' so macOS dock-activate doesn't
drop the recovery surface (window recreated with stale recoveryStore.mode)
- Hoist setOnQuitRequested before createWindow so synchronous boot failures
reach a wired Quit handler
Three polish items:
- Tray's Change Instance now routes through handleRecoveryAction so both
paths share one implementation; recovery action's change-instance also
show()+focus() for hidden-window tray clicks
- install-update action guards against state.updateState !== 'downloaded'
(defense in depth against malicious or buggy renderers)
- Object.freeze rationale documented in RecoveryStateStore.update
