- Add workspace-mcp >= 1.20.0 to pyproject.toml (pulls google-api-python-client etc. transitively)
- Remove redundant google-api-python-client/google-auth/google-auth-httplib2 direct deps
- Rewrite google_workspace.py: single Secrets Manager call per tool (client_id/client_secret
are already in the credentials secret stored by oauth-handler, no separate oauth-client secret needed)
- Mirror workspace-mcp output format for list_calendars and get_calendar_events
- Add body_format param to get_gmail_message (text/html/raw) matching workspace-mcp API
- Update uv.lock
