chore: extend .gitignore with AI assistant configurations and caches

18 tests covering:
- channel_ctoken_v5 protobuf token generation per tab
- shortsLockupViewModel parsing (id, title, thumbnail, type)
- View count formatting with K/M/B suffixes
- extract_items with reloadContinuationItemsCommand response format

All tests run offline with mocked data, no network access.
