v0.3.9: Add configurable issue label and debug mode
This release adds more flexibility to the issue-fix mode:
Improvements:
- Added configurable issue label (default: 'claude-fix')
- Added debug mode option to enable shell tracing and Claude debug output
- Improved code to handle the new options
- Updated documentation to reflect these new options
These changes make it easier to integrate the action into your workflows by allowing customization of the labels that trigger the action and providing better debugging capabilities when troubleshooting issues.
