- Add agent/google_workspace_oauth.py: PKCE OAuth module with bundled Nous client ID (placeholder), local fallback server, dashboard integration, headless mode, token refresh, and revocation - Add 'hermes auth google-workspace login/status/logout' CLI commands - Add 'hermes auth add google-workspace' redirect to login flow - Add Google Workspace to dashboard OAuth providers card with server-side callback at /auth/google/callback - Dashboard PKCE flow: auto-redirect callback, session polling, auto-close modal on success - Branded callback pages (dark teal theme matching dashboard) - Disconnect uses in-app modal instead of browser alert dialog - CLI delegates to dashboard when running (single source of truth) - Falls back to headless mode with --no-browser when dashboard is down - Middleware bypass for google-workspace start/poll endpoints (CLI access)
