Add contact-aware feed scope

Browse source 
- src/feed.rs: contact_feed + contact_pubkeys fetch the active profile's
  kind 3 contact list and aggregate notes only from those authors;
  aggregate_for + FeedBuilder accept an optional author whitelist
- IPC: FeedGet accepts contacts_only, resolves the active profile npub
- CLI: feed --contacts [limit] filters to the active profile's contacts
- Frontend: Feed screen Everyone/My contacts toggle, scope-aware empty
  states, feedGet(limit, contactsOnly) threading
- Tests for author filtering and the contacts scope in feed.rs and
  FeedScreen.test.tsx
