feat(app): content detection overhaul, apps tab, chat UX, web search

- Overhaul content detection: expand all query/response classifiers with
  broader AI response patterns (news, music, books, TV, places, websites)
- Add Nostr detection (isNostrQuery, isNostrLikeResponse) and App detection
  (isAppQuery, isAppLikeResponse) classifiers
- Add bare domain extraction from AI text (e.g. "check out damus.io")
- Add Apps tab with curated database of ~30 Nostr + Bitcoin ecosystem apps
  (clients, wallets, privacy tools, node software, dev tools)
- Create AppsGrid + AppDetail components with search, filtering, how-to
- Wire app extraction and Nostr detection into useContentPanel
- Add PromptIndex badges for Apps and Nostr tabs
- Chat UX: dedicated history button, settings modal (memory + advanced),
  fix collapsed chat v-if/v-else chain bug
- Web search: add Brave Search API as primary backend, expand SearXNG pool
- iOS HIG: comprehensive mobile UX rules in cursor rules + CLAUDE.md
