研究方向
The method `bring to front and focus` was added to the `WindowHandler` trait in PR #293 but implementations for concrete window types are missing. Start by examining the existing implementations of other `WindowHandler` methods in the codebase (e.g., in `platform/` directory) to understand the pattern. Then implement the method for each platform (e.g., Windows, macOS, Linux) by filling in the appropriate platform specific code. No linked PRs or additional comments exist, so the implementation should follow the existing style.
