Expand App Intents: dialogs, search type, mutating intents (#17)

Addresses the three open items on the App Intents ticket:

- Check Status / Check Builds now return a spoken/visible dialog alongside
  their value, so they surface a result in Siri instead of appearing to do
  nothing. Logic consolidated to always produce a message.
- Search Hutch gains a Search Type parameter (user, git/hg repo, mailing
  list, tracker, build job) threaded through the .search route into Lookup,
  which pre-selects the type. LookupType now conforms to AppEnum.
- Adds mutating intents (not just navigation): Clear Recent Activity and
  Unpin Resource, backed by RecentActivityStore.clear and a new
  HomePinStore.removePin. Both act on the active account's storage.

Tests cover search-type routing, the blank-query fallback, and pin removal.
