Pull request overview

This PR replaces a custom GitHub Actions script with the standardized actions/stale@v10 action to automate closing of inactive issues. However, the new configuration significantly changes the repository's issue management behavior and may conflict with existing policies.

Key Changes:

• Replaces custom JavaScript-based workflow with actions/stale@v10 action
• Changes from targeting specific "Needs Author Feedback" labeled issues to ALL open issues
• Extends inactive period from 7 days to 44 days (30 days until stale + 14 days until close)
