[q] lint-monster: skip-if recent open issues (24h), single agent session

Discussion: #32740

Changes Made

.github/workflows/lint-monster.md

1. Skip-if recent open issues (24h expiration)

Added a new skip_check step before lint_scan that:

• Uses gh issue list to find open [lint-monster] issues created within the last 24 hours
• If any are found, creates lint-clean.flag to cause the agent to call noop and stop
• Updated lint_scan to respect a pre-existing lint-clean.flag (from skip_check)

This prevents the workflow from spawning duplicate agent sessions when lint issues from the previous run are still open and being worked on. The 24h window ensures the workflow can run again the next day even if issues remain open.

2. Single agent session per run

• Reduced assign-to-agent: max from 3 → 1
• Updated agent prompt: select one focused group (≤ 10 diagnostics or a single linter rule) instead of up to three groups
• Changed prompt to assign exactly one Copilot agent session

This makes each daily run scoped to what a single agent session can realistically complete, avoiding overloading the issue tracker with parallel assignments that may conflict.

Validation

All modified workflows compiled successfully:

• ✅ lint-monster — valid, no errors, no warnings

Note: .lock.yml files will be regenerated automatically after merge.
