Andrey Antukh 5b02e4d898 ✨ Add find-project-anomalies skill and helper
Check a milestone against the Main project board with
scripts/project-anomalies.py (check writes
tmp/<MILESTONE>-ANOMALIES.md): open issues with merged PRs,
milestone mismatches either way, needs triage labels and
unassigned non-community issues. Outsiders resolve in bulk;
only a missing milestone auto-fixes, on confirmation.

Teach scripts/gh.py batched issue lookup (issue subcommand),
milestone on prs output, plus assignees and projects fields,
and retry transient HTTP 504s.

"""
project-anomalies.py — Find anomalies on the Main project board for a milestone.
Used by the ``find-project-anomalies`` skill. Fetches milestone issues and
PRs in bulk via ``scripts/gh.py`` (one GraphQL call per 50 items, never one
call per item) and writes a clickable report to
``tmp/<MILESTONE>-ANOMALIES.md``.
Anomaly types (all scoped to the given milestone):
1. open-with-merged-pr — OPEN issue with a MERGED closing PR.
2. issue-pr-mismatch — milestone issue whose closing PR is in a different
milestone (or none), or issue not associated to the Main project.
3. pr-issue-mismatch — milestone PR whose closed issue is in a different
milestone (or none), or not associated to the Main project.
4. needs-triage — MERGED PR whose closed issue has the `needs triage` label.
5. unassigned — MERGED PR whose closed issue has no assignees and no
`community contribution` label (on the issue or the PR).
Project membership is only checked on the issue side: PRs are not the unit
tracked on the Main board, so an unprojected PR alone is never an anomaly.
Usage:
python3 scripts/project-anomalies.py check "2.17.0"
python3 scripts/project-anomalies.py check "2.17.0" --output tmp/2.17.0-ANOMALIES.md
Prerequisites:
- gh CLI authenticated (gh auth status)
- Python 3.8+
