Add GitHub Workflow to Automatically Close Issues

[GautamBytes]

Problem

Currently, when PRs are merged that fix issues, the related issues remain open even though they've been resolved. This creates:

• Confusion about which issues are actually still open
• Manual overhead for maintainers to close resolved issues
• Inconsistent issue tracking across the project

Proposed Solution

Add a GitHub Actions workflow that will:

Automatic Mode (Future PRs)

• Automatically close issues when PRs are merged to main
• Detect issue references in PR titles and descriptions using keywords like:
  • fixes #123
  • closes #456
  • resolves #789
• Add explanatory comments to closed issues

Manual Mode (Current Cleanup)

• Allow maintainers to manually close multiple issues at once
• Useful for cleaning up issues that were already fixed but not closed

Benefits

• Reduces manual work: No need to manually close issues after PR merges
• Improves project organization: Keep issue tracker accurate and up-to-date
• Follows GitHub best practices: Using standard linking keywords
• Flexible: Works both automatically and manually as needed

Implementation

• Single workflow file: .github/workflows/close-issues.yml
• Uses GitHub's built-in GITHUB_TOKEN (no additional setup required)
• Follows existing project formatting standards
• Includes error handling and logging

Usage for Contributors

Contributors just need to include standard GitHub linking phrases in their PRs:

• "This PR fixes X"
• "Closes #456 and resolves Y"
• "Fix for issue Z"

No additional workflow or process changes required.
