This service ingests domain-wide Gmail into BigQuery for the Envision context layer.
Deploys are automated: push to main triggers .github/workflows/deploy.yml
which uses Workload Identity Federation (no service-account JSON keys) to ship
to Cloud Run, then re-creates the gmail-scraper-5min scheduler.
For local dev, use gcloud auth application-default login — never copy SA
key files into this repo.
Operational details, BigQuery schema, and downstream MCP consumers live in
README_CLOUDRUN.md.
