"""Tests for the google_meet plugin.

Covers the safety-gated pieces that don't require Playwright:

  * URL regex — only ``https://meet.google.com/`` URLs pass
  * Meeting-id extraction from Meet URLs
  * Status / transcript writes round-trip through the file-backed state
  * Tool handlers return well-formed JSON under all branches
  * Process manager refuses unsafe URLs and clears stale state cleanly
  * ``_on_session_end`` hook is defensive (no-ops when no bot active)

Does NOT spawn a real Chromium — we mock ``subprocess.Popen`` where needed.
