fix(brain): drop --approval-mode yolo from Gemini CLI search

yolo auto-approves every tool call, so a real-time search query could in
principle trigger write/shell tools. Default approval mode still auto-runs the
CLI's read-only web search in headless mode but never silently approves
destructive tools. Verified end-to-end: a grounded query returns a current
answer in ~23s with the account OAuth login. Test asserts yolo is absent;
specs and docs/llm_contexts.md updated.

-## To finish / verify
-- Provide `GEMINI_API_KEY` to build + verify the false-mode path (a real call is

-- Wire `config.py` + the two Python tools + registry, update specs and

+## Notes / verification
+- Grounded Gemini search needs real quota. On a free tier the grounded call can
+  return HTTP 429 `RESOURCE_EXHAUSTED` (free-tier limit 0); the OAuth login must
+  be a Google account with usable Gemini quota, otherwise the path 429s and
+  fail-opens to DDG. The 30s subprocess timeout bounds the CLI's retry/backoff.
+- Behaviour covered by `tests/test_realtime_gemini_cli.py`.
