研究方向
Identify Python files in the repository that use `if isinstance(...)` statements. Convert each to `match case` syntax, ensuring all branches are covered. Run existing tests to verify no regression. Since no specific files are mentioned, start by searching the codebase for `isinstance` calls and assess if pattern matching can be applied.
