agy(gemini): RTFM audit — confirmed healthy, version + verified-date refresh

Audited the Gemini wrapper against the CLI's bundled help/README (gemini 0.45.2),
same pass as the grok skill. Unlike grok, found NO functional bug:
- All flags correct and real: -p, --skip-trust, -o json, --approval-mode plan|yolo,
  --include-directories, -m (verified against `gemini --help`).
- JSON schema {session_id, response, stats} -> .response confirmed via live probe.
- Pinned model gemini-3.1-pro-preview STILL VALID (live PONG); the GA-looking
  gemini-3.1-pro and gemini-3-pro both ModelNotFoundError -> keep the -preview suffix.
- Default text model is gemini-3.1-flash-lite (by design; verify/review/search/image
  pin pro). No thought-suppression flag exists in the CLI, so the gresponse() reasoning
  -leak scrub stays (justified, signature-gated, byte-exact otherwise).
- Live `search` re-validated end-to-end through the wrapper (58s, grounded sources).

Only change: version 0.45.1 -> 0.45.2 in SKILL.md + wrapper header, and refreshed the
verified-date notes with the 2026-06-17 re-validation findings.
