* Update failed-compatibility-macos-latest.json

* Fix JSONDecodeError when loading empty failed-compatibility files

Add defensive error handling to load_failed_compatibility() to gracefully
handle empty or corrupted JSON files instead of crashing with JSONDecodeError.

This prevents the remove-incompatible-packages workflow from failing when
encountering edge cases with the failed-compatibility JSON files.

Changes:
- Check for empty file content before parsing JSON
- Wrap json.loads() in try-except to catch JSONDecodeError
- Log warnings/errors when encountering problematic files
- Return empty dict as fallback in all error cases
