fix: address all Gemini code review comments on PR #457

- Use --delete-branch flag with gh pr close instead of manual Git API
  branch deletion (removes delete_branch function entirely)
- Fix reviewer attribution in retrospective.md (remove incorrect model version)
- Replace debug print() with logger.info() in generate_ux_suite.py
- Note: LearningAgent IS in wrangler.jsonc v1_sentinel migration (line 470),
  Gemini's comment was a false positive
