Implement v4.6.0: sweep Live Activity, share extension, iPad split view, actionable notifications

- Sweep Live Activity: SweepActivityAttributes (Shared/), lock-screen + Dynamic
  Island UI in the widget extension, driven by SweepActivityController wired into
  the batch pipeline (begin/update/end); NSSupportsLiveActivities in Info.plist.
- Share extension (DomainDigShareExtension): accepts a web URL from the share
  sheet, extracts the host, and hands it to the app via the App Group inbox
  (DomainDigShareInbox); the app consumes it on activation and inspects it.
- iPad layout: RootTabView uses NavigationSplitView in the regular size class
  and the tab bar in compact.
- Actionable notifications: per-domain threadIdentifier grouping, a Re-inspect
  action, and tap routing into the domain detail via the intent router.
- Bump version to 4.6.0 (build 38) across app, widget, and share targets.
