Refactor Google Meet Transcripts Extension for Local Use

- Removed all cloud-related functionalities, including login prompts and token handling.
- Disabled Laxis cloud features, ensuring no data is sent to external servers.
- Updated manifest to reflect the new local-only functionality.
- Added a new Python server to handle transcripts locally, including WebSocket support.
- Implemented storage management for transcripts, including deduplication and file writing.
- Created a smoke test for the WebSocket server to simulate transcript updates.
- Updated README with setup instructions and usage details for the new local server.
