name: AI Agent Integration Tests

# Exercises the AI agent flow path (preview_flow with `aiagent` modules) against
# real LLM providers. Runs only when AI-agent backend code or the tests change,
# because each run makes real (paid) LLM calls. To avoid spending on every commit,
# the PR side triggers only when a PR is marked ready for review (out of draft) —
# not on `synchronize` — plus push to main and manual dispatch.
