Subject: Complete v4.5.0: Run Sweep intent, detail deep link, and portfolio
 widget

Finishes the v4.5.0 "Home Screen & Shortcuts reach" scope that the tag shipped
partially:

- Add RunSweepIntent (opens the app and runs refreshAllTrackedDomains via the
  in-process router) and expose it in DomainDigShortcuts.
- Extend the domaindig:// scheme with `sweep` and `domain` (detail) actions;
  route .detail to present TrackedDomainDetailView and .sweep to refresh the
  watchlist. Move DomainDigDeepLink into Shared/ so the widget can build links.
- Add a WidgetKit extension (DomainDigWidgetExtension) with small/medium/large
  Portfolio widgets showing health counts, per-domain status, and certificate
  countdowns; tapping a domain deep-links into its detail.
- Share portfolio state via an App Group (group.net.cleberg.DomainDig): the app
  writes a DomainDigWidgetData snapshot on launch/foreground and on watchlist
  changes and reloads timelines; the widget reads the same store.
