• Reviewed the Workflow System Overview to confirm Gate / gate is the required status and Maint 46 Post CI is informational after merge.
• Checked this pull request's Checks tab to confirm Gate / gate appears under Required checks (Health 45 Agents Guard auto-adds when agents-*.yml files change).
• Escalated via the branch protection playbook if Gate / gate is missing or Maint 46 Post CI shows up as required.
• Confirmed the latest Gate run is green (or linked the failing run with context).

Pull Request Overview

This PR fixes the keepalive workflow to resume nudging pull requests after command response timeouts. The key change is adding a time-based threshold so that if an agent hasn't responded to a command within the idle timeout period, keepalive comments will resume.

Key changes:

• Added time-based logic to resume keepalive nudges when commands become stale (exceed idle timeout)
• Created new test scenario validating the stale command handling behavior
