wait-for-github
Reference for the safe two-phase GitHub event wait pattern. Use when a skill needs to block on a GitHub PR event (merged, CI complete, review submitted) without hitting GraphQL rate limits. Replaces `gh pr view --json` polling loops with `catalyst-events wait-for` plus a REST-only fallback. Includes a 3-minute diagnostic checkpoint to detect silent filter mismatches before they cause multi-hour stalls.
