"""google_meet plugin — let the agent join a Meet call, transcribe it, follow up.

Headless Chromium (Playwright) joins the URL, enables live captions and scrapes them into a
transcript. Realtime mode adds agent speech (OpenAI Realtime + virtual audio device); remote
nodes run the bot on another machine. Explicit-by-design: only joins ``https://meet.google.com/``
URLs passed in — no calendar scanning, auto-dial or consent announcement.
