chore(ci): add PR autocloser

[jdx]

Summary

• add a scheduled PR autocloser workflow
• close inactive PRs after 7 days only when they have failing checks or merge conflicts
• keep exclusions for @jdx-authored and keep-open PRs

Validation

• actionlint .github/workflows/pr-closer.yml
• git diff --check
• jq filter sample validation

---

Note

Medium Risk
Automates closing pull requests via the GitHub API based on status/merge state; misclassification or query mistakes could close PRs unexpectedly, though it’s limited to stale PRs and excludes keep-open and jdx-authored PRs.

Overview
Adds a new scheduled/dispatchable GitHub Actions workflow (pr-closer) that scans for open PRs not updated in ~7 days (excluding jdx-authored, keep-open, and draft PRs) and automatically closes those with failing checks and/or merge conflicts.

PRs with cancelled checks or unknown merge state are only logged (skipped), and the workflow runs with minimal PR/check/status read/write permissions plus concurrency to prevent overlapping runs.

Greptile Summary

Adds a new daily GitHub Actions workflow (pr-closer) that finds open, non-draft PRs inactive for 7+ days (excluding @jdx-authored and keep-open-labeled ones) and closes those with failing checks and/or merge conflicts, while only logging a warning for cancelled-check or unknown-merge-state cases.

• The CUTOFF date math is correct: date -d '6 days ago' produces a date such that updated:<$CUTOFF matches PRs last touched 7+ days ago, consistent with the "at least 7 days" closing comment.
• The jq pipeline handles null statusCheckRollup safely via // [] fallbacks, and gh pr close failures are caught with || echo \"Warning: ...\" so a transient error on one PR doesn't abort the rest of the batch.
• Permissions are minimal and appropriately scoped; concurrency: cancel-in-progress: true prevents overlapping scheduled runs.

Confidence Score: 5/5

Safe to merge — the workflow is well-scoped, uses minimal permissions, and correctly handles partial failures.

The workflow logic is sound: the date math correctly targets PRs inactive for 7+ days, the jq pipeline is null-safe, the || echo guard prevents a single close failure from aborting the batch, and exclusions for the repo owner and keep-open label are in place. Both issues flagged in the previous review round have been addressed.

No files require special attention.

Important Files Changed

Filename	Overview
.github/workflows/pr-closer.yml	New scheduled workflow that auto-closes inactive open PRs (≥7 days, non-draft, non-jdx, no keep-open label) that have failing checks or merge conflicts; jq logic is null-safe, the close command has proper error handling, and permissions are correctly scoped.
