Extends the compare_file_contents tool with AST-based structural
diffing for code files using tree-sitter. Instead of line-based diffs,
this shows declaration-level changes (functions, classes, types) which
gives models more concise and semantically meaningful context.
Supported languages: Go, Python, JavaScript, TypeScript, Ruby, Rust,
Java, C/C++.
Requires CGO_ENABLED=1 for the tree-sitter C bindings. Windows builds
are removed from goreleaser as CGO cross-compilation is not supported
without additional toolchain setup.
For unsupported languages, falls back to unified line-based diff.
