DomainDig v4.5.0: Add App Intents, Shortcuts, and a domaindig:// deep link

- Add InspectDomainIntent that runs the headless inspection pipeline and
  returns a summary for Shortcuts, Spotlight, the Action button, and Siri
- Add AddToWatchlistIntent that opens the app and tracks a domain through the
  existing premium-checked path via an in-process router
- Register the domaindig:// URL scheme with inspect/watch deep links routed in
  RootTabView (onOpenURL)
- Expose both intents through DomainDigShortcuts (AppShortcutsProvider)
- Bump AppVersion/marketing version to 4.5.0 and build number to 37
