Pull request overview

This pull request introduces automation to manage stale issues and pull requests in the repository. A new GitHub Actions workflow will run daily to identify inactive items (28 days without activity), label them as "stale," notify contributors, and automatically close them after an additional 7 days of inactivity if no response is received. This helps maintain repository health by preventing accumulation of abandoned contributions.

Changes:

• Added a scheduled GitHub Actions workflow that runs daily at midnight
• Configured stale bot with 28-day inactivity threshold and 7-day grace period before closure
• Set up automated messaging and labeling for both issues and pull requests
