## Why upgrade?

Keeping GitHub Actions up to date ensures:
- **Security**: Latest security patches and fixes
- **Features**: Access to new functionality and improvements
- **Compatibility**: Better support for current GitHub features
- **Performance**: Optimizations and efficiency improvements

### Security Note

Actions that were previously pinned to commit SHAs remain pinned to SHAs
(updated to the latest release SHA) to maintain the security benefits of
immutable references.

### Testing

These changes only affect CI/CD workflow configurations and should not
impact application functionality. The workflows should be tested by
running them on a branch before merging.
