XcodeGen merged Localizable.strings into the main app only, so the keyboard
extension had no .lproj files and NSLocalizedString returned raw keys. Use a
dedicated Keyboard.strings table and explicit buildPhase: resources entries.
Refresh mic/speech status when returning from TCC dialogs, persist onboarding
page across Settings trips, load extension strings from .lproj bundles via
ExtL10n, and keep flow result polling alive across host-app jumps.
Remove KeyboardL10n hard-coded fallbacks in favor of ExtL10n and extension
Localizable.strings. Add Flow session expiry hints, Darwin cross-process
notifications, session monitor on the keyboard, and app icon on GitHub Pages.
