- Add latest tag push alongside SHA tag for manual rollback/debugging
- Reduce log retention from 3 to 1 day
- Comment out bot_error_metrics and alerts to save ~$0.47/month
- Minor whitespace fix in cd.yml
Update GitHub Actions workflows to rely on repository variables and simplify build/deploy logic. cd.yml: switch secret/project lookups to vars, adjust workflow_run detection for auto-deploy, remove derived secret outputs, resolve Artifact Registry image tags from the triggering SHA, and use vars for Google Cloud auth and project references. ci.yml: add dev to PR branches, condense the quality matrix commands, rework the images job to authenticate and push only on branch pushes while doing build-only on PRs (with proper cache usage), add id-token permission, and introduce a final CI gate job that aggregates job results to block CD when CI fails. Also includes minor formatting and whitespace cleanups.
