* test(e2e): add Gmail skill end-to-end tests

- Introduced a comprehensive end-to-end test suite for the Gmail skill, covering the full lifecycle from discovery to OAuth completion and email management.
- Implemented two modes: a lifecycle-only mode that validates the skill's event loop without real credentials, and a live mode that interacts with the Gmail API using actual credentials.
- Added detailed environment variable requirements and usage instructions for both testing modes.
