Bump version to 7.1.13

Enhanced error handling and logging improvements:
- Standardized error messages across hooks and worker service
- Platform-aware restart instructions (macOS, Linux, Windows)
- Fixed false error logging from happy_path_error misuse
- Timezone-aware logging (uses local machine timezone instead of UTC)
- Comprehensive test coverage for error handling scenarios
