* feat(google): add search, suggest, news, and trends adapters
Four new commands under `google`:
- search: browser-based DOM extraction from google.com/search
- suggest: public JSON API (suggestqueries.google.com)
- news: public RSS feed (top stories + keyword search)
- trends: public RSS feed (daily trending searches by region)
Shared RSS parser in utils.ts with attribute/CDATA support.
Unit tests for parseRssItems, E2E tests with network skip guards.
* refactor(google): downgrade search strategy from COOKIE to PUBLIC
Google search results are public data, no login needed. Browser is
required for DOM rendering, not authentication. Standalone mode
confirmed working in testing.
* fix: update test comment to reflect PUBLIC strategy
