spideystreet 127b4caf0d feat(skills): migrate google-workspace to gws CLI backend
Migrate the google-workspace skill from custom Python API wrappers
(google-api-python-client) to Google's official Rust CLI gws
(googleworkspace/cli). Add gws_bridge.py for headless-compatible
token refresh. Fix partial OAuth scope handling.
