fix: end-to-end agent testing on this PR

- Fix system prompt: use concrete example instead of <filepath> placeholder
  (LLM was interpreting angle brackets literally)
- Fix filepath parsing: handle remaining edge cases
- Remove hardcoded test values, use PR's own CI failures
- Add aiohttp==3.9.0 to Dockerfile to trigger CVE scan failure
- Skip branch validation for pull_request events

TODO after validation: remove pull_request trigger, remove aiohttp, restore branch validation
