Adopt Antigravity PR-generator agent with safer concurrent DB workflows

This nightly adds an Antigravity PR-generator agent runner with prompt templates, Firestore dual-locking and test ingestion utilities, plus a core fix that skips merged function-response turns when resolving the active loop—use these to harden agent-driven PR automation.

Why this loop

The release signal centers on pr-generator-agent (Antigravity runner and prompt templates) and pr-generator-db (Firestore concurrency dual-locking and test ingestion utilities), alongside a core loop fix for merged function-response turns. Teams already automating PR creation can reduce race conditions on shared Firestore state, standardize agent prompts via the new templates, and validate ingestion paths with the test utilities. The active-loop fix improves reliability when tool/function responses are merged, which matters for multi-turn agent runs that drive PR generation. Treat this as a prerelease: pilot on non-critical repos first, measure lock contention and loop correctness, then roll out wider.

Proposed actions

  1. Pilot the Antigravity PR-generator agent runner on a low-risk repo using the new prompt templates; capture where templates need team-specific edits
  2. Enable Firestore dual-locking for any shared pr-generator-db usage so concurrent agent runs do not clobber each other’s locks
  3. Wire the test ingestion utilities into CI or local checks before promoting agent-generated PRs
  4. Re-test multi-turn tool/function flows after the core fix that skips merged function-response turns when finding the active loop; confirm loops no longer stall or mis-identify the active turn
  5. Document ownership and rollback for this nightly path given prerelease tags before wider team adoption
