What Changed

• Updated Dependabot auto-merge workflow to use actions/checkout@v4 and actions/create-github-app-token@v1
• Modified stale issue/PR check workflow to use actions/stale@v9 with updated configuration parameters
• Synchronized label management workflow to use actions/checkout@v4 and micnncim/action-label-syncer@v1
• Refreshed workflow configurations to align with current GitHub Actions best practices and security standards

Why It Was Necessary

• Ensures workflows use maintained and secure versions of GitHub Actions
• Incorporates latest security improvements and bug fixes from action dependencies
• Maintains consistency with upstream workflow patterns and reduces technical debt
• The stale workflow update includes improved configuration for issue and PR staleness detection

Testing Performed

• Validated YAML syntax in all three modified workflow files
• Verified workflow action versions exist and are published in GitHub Actions marketplace
• Confirmed workflow trigger conditions (schedule, pull_request, push) remain functionally equivalent
• Reviewed action parameter compatibility between old and new versions

Impact / Risk

• Low Risk: Standard GitHub Actions dependency updates with no logic changes
• No Breaking Changes: Workflow triggers and core functionality remain unchanged
• Security Improvement: Updated actions include latest security patches and improvements
• CI/CD Impact: Workflows will use newer action runtimes but maintain same behavior
