[ai] fix(ci): support stale batch in branch-cleanup-delete.sh

[github-actions]

Selected checkpoint

Failing GitHub Actions workflow run (highest-priority candidate per the
selection policy: recent failing workflow on main).

• Workflow: Branch Cleanup
• Run: https://github.com/groupthinking/EventRelay/actions/runs/34392035516
• Trigger: workflow_dispatch (batch=stale, dry_run=1)
• Conclusion: failure (exit code 2)

Root cause

.github/workflows/branch-cleanup.yml's workflow_dispatch input exposes
options: [safe, stale, review], and the branch-cleanup skill's verdict rule
(.claude/skills/branch-cleanup/SKILL.md) defines a CLOSE-STALE verdict.
But scripts/maintenance/branch-cleanup-delete.sh's case statement only
implemented safe|review. Selecting stale — exactly what run 34392035516
did — always falls through to the *) branch, prints
usage: ... {safe|review}, and exits 2, failing the job.

Fix

Added a documented (currently empty) STALE_BRANCHES array and a stale)
case that safely no-ops when there are no CLOSE-STALE branches in the
current docs/branch-cleanup-matrix.csv audit, instead of erroring. This
matches existing SAFE_BRANCHES/REVIEW_BRANCHES wiring, so a future audit
that populates CLOSE-STALE verdicts only needs to fill in the array — the
dispatch path already works.

Canonical mapping

• Issue: none found (searched gh api search/issues for
  branch-cleanup-delete.sh + stale; no open issue or PR duplicates this).
• PR: this PR
• Branch: fix/branch-cleanup-stale-batch

Verification (current head)

bash -n scripts/maintenance/branch-cleanup-delete.sh                     # syntax OK
DRY_RUN=1 scripts/maintenance/branch-cleanup-delete.sh stale             # "no CLOSE-STALE branches..." exit 0
scripts/maintenance/branch-cleanup-delete.sh bogus                       # usage error, exit 2 (unchanged)
shellcheck scripts/maintenance/branch-cleanup-delete.sh                  # clean, exit 0
python3 -m pytest tests/unit/test_gh_aw_workflow_governance.py -q --no-cov  # 11 passed

Evidence chart

Failing/actionable-run signal for the audit window, with the selected
checkpoint highlighted:

Recommended pattern: Autoloop

This checkpoint was a small, bounded, single-file CI script bug surfaced by
one scheduled/dispatched Actions workflow. The fix cycle was
detect-failure → patch → verify → land, with no multi-agent coordination,
no natural-language Actions authoring, and no need for a
collaboration-platform continuous-AI narrative. Autoloop — simple,
goal-driven iterative automation — is the best fit for EventRelay on this
class of problem right now; Chopin (real-time multiplayer agentic
planning) and Agentic Workflows (NL-programmed Actions) would be
over-engineering for a one-line dispatch-argument bug, and Continuous AI
doesn't apply since there's no cross-repo/platform collaboration surface
involved.
