Enhance stale PR auto-close to handle failed workflows

[DenizAltunkapan]

• I have read CONTRIBUTING.md.
• This pull request is all my own work -- I have not plagiarized it.
• All filenames are in PascalCase.
• All functions and variable names follow Java naming conventions.
• All new algorithms have a URL in their comments that points to Wikipedia or other similar explanations.
• All new code is formatted with clang-format -i --style=file path/to/your/file.java

This PR updates the GitHub Action for automatically closing stale pull requests.

Previously, only failed checks were considered when determining whether a PR should be closed. Now, failed workflow runs are also taken into account.

Changes:

• Fetch workflow runs for each PR.
• Close PRs if there are failed checks or failed workflows and no recent meaningful activity.
• Improved logging for better visibility of the decision process
