[Gastown] Refinery not auto-monitoring PRs per config rules

[Xyrces]

What happened?

The refinery is not following the polling and monitoring rules defined in .gastown/refinery.config.md.

Config specifies:

• Poll interval: 60 seconds
• Monitor for: new comments, review submissions, status checks
• Continue iterating until review summary says "ready to merge"
• Address comments, resolve threads, push fixes
• Merge when approved or 10min silence

Actual behavior:

• Refinery goes idle after initial PR creation
• Does not poll for new review comments
• Does not auto-address comments
• Does not merge when review is ready
• Requires manual nudge/reassign to wake up

Expected behavior:
Refinery should continuously monitor assigned PRs in a loop:

1. Check for new comments/reviews every 60s
2. If kilo-code-bot left review comments, address them in code
3. Resolve comment threads via GitHub API
4. Push fixes and continue monitoring
5. When review summary comment contains "ready to merge" → merge PR
6. Only stop monitoring when PR is merged or closed

Impact:
Manual intervention required for every PR. The automated review→fix→merge loop is broken.

Repro:

1. Create bead that results in PR
2. Wait for kilo-code-bot review
3. Refinery does not auto-address comments
4. PR sits open until manually nudged
