### Major Improvements
- **Async initialization refactoring**: Complete async migration of init_config, improving app startup performance and stability
- Change init_work_config from blocking to async execution
- Optimize error handling for directory creation and config file initialization
- Enhance structure and robustness of initialization process
- **Logging system standardization**: Unify usage of project's built-in logging! macro
- Replace all log::info!/warn!/error!/debug! with logging!(level, Type::Setup, true, ...) format
- Maintain consistency in log categorization and formatting
- Improve convenience for log tracking and debugging
### Technical Optimizations
- **Error handling improvements**: Remove crate::log_err! macro, use standard Result error propagation
- **Directory management optimization**: Refactor ensure_directories function with clearer directory creation logic
- **Config initialization enhancement**: Separate initialize_config_files function for better code maintainability
- **Async task management**: Use AsyncHandler::spawn to optimize background log cleanup tasks
### Bug Fixes
