Hello,

I notice bat command is very slow, maybe we can use tree-sitter to provide syntax highlight, tree-sitter is very fast.

研究方向
Review the current syntax highlighting implementation in bat (likely using syntect). Investigate how tree sitter can be integrated as a backend, starting with the documentation and examples in the tree sitter repository. Compare performance benchmarks between syntect and tree sitter for common file types. Check existing discussions in the issue for any proposed architecture or concerns.
