Claude Code: Fix STATUS_FILE path - use Path(__file__).parent instead of os.getcwd()

- Changed error_handlers.py to use absolute path based on file location
- Matches pattern used in brain_minimal.py for consistency
- Resolves discrepancy between local (/tmp/claude-workpace) and container (/app) paths
