- add getValidGoogleAccessToken helper and use it in email-cron, email account auth resolver, and the new gmail proxy
- POST /api/integrations/google/gmail-proxy forwards arbitrary gmail rest calls server-side, with auto-refreshed oauth
- pi-manager and claude user-instance inject OFFICER_API_URL + per-session JWT so tools can call back as the user
- claude anthropic proxy uses Authorization: Bearer + preserves any anthropic-beta headers (pro oauth tokens are rejected via x-api-key, and overwriting the beta header broke context_management)
- pi --list-models: fall back to stderr when stdout is empty (pi v0.73.1 writes the table to stderr)
- mcp tool server + pi tool loader: accept type: object inputs so json bodies stay structured
