Refactor: Fix Event Buffer Deadlock with State Machine (#1633)

* feat: implement state machine for chat synchronization and buffer management

* test: Add Jest configuration and tests for connection deadlock handling

- Created a Jest configuration file to set up testing environment.
- Implemented utility functions for creating isolated authentication sessions and mocking WebSocket connections.
- Added a test case to ensure that the connection does not deadlock when history sync is disabled, verifying the correct handling of message events.

* feat: add GitHub Actions workflow for running tests

* chore: sort import lint

* fix: implement timeout handling for AwaitingInitialSync state in chat socket, maybe fix memory leak

* feat: enhance chat synchronization by refining AwaitingInitialSync handling and adding history sync checks
