What Problem This Solves

Eleven Google Meet implementation declarations were exported even though they have no repository consumers and are not re-exported by the plugin entrypoint.

Why This Change Was Made

Keep CLI manifest shapes, internal Meet API response types, the OAuth token result, the realtime strategy alias, and the audio buffer constant local to their owning modules. The exported runtime functions and supported plugin entrypoint remain unchanged.

User Impact

None. This is export-surface cleanup only; Google Meet CLI, config, OAuth, API, and transport behavior are unchanged.
