Closes CL-11843 (https://linear.app/abklabs/issue/CL-11843/add-the-corbits-triage-policy-to-corbits-builder).

Changes

Adds .corbits-triage.yml:

• Process rules:
  • A linked GitHub or Linear issue is required. A pull request without one gets a comment to open an issue first, then is closed. Other failures request changes.
  • Also checked: Conventional Commits, CI green, no merge conflicts, no co-author lines or AI attribution, no hidden text, no duplicates. "Focused on one thing" only labels.
  • Rejected outright: node_modules, env files, dist, *.db, tmp/, .tmp/ and .data/.
• Sensitive paths: vendor/, patches/, migrations and auth are high; CI, deploy and bun.lock are labelled.
• Code rules on added code:
  • Fail: the convention preset (IIFEs, promise chains, empty catches, nested ternaries, ?? 0, ?? [], suppression comments).
  • Fail: a catch without a binding, or one whose error is neither used nor rethrown.
  • Fail: reaching vendored Interchange source by path, through an import, re-export or dynamic import.
  • Fail: invented empty fallbacks (|| [], || {}, ?? {}, empty strings, || 0), except inside string building and arithmetic.
  • Ask a maintainer: hand-rolled sleeps, and the interface opening a stream outside openSharedEventSource.
• Actions: approve passing pull requests from thegreataxios and brianjfox; assign unsure ones to thegreataxios.
• Off: code review and size checks.

Verification

• Triage's policy reader (policy-check-action) reports the file as valid.
• Triage's local check (cli.ts check) was run on a throwaway commit:
  • It failed or flagged every code rule: path import, bare catch, dropped error, invented fallback, Bun.sleep and new WebSocket.
  • It passed 1 + (n || 0) and ${s ?? ""}.
• An independent review's findings are fixed.
• CI passed.
