`WITFormatter` renders a parsed WIT AST back to text matching `wasm-tools component wit --all-features --no-docs`, so WIT can be pretty-printed and round-tripped through parse and format. The test suite pins our parser and formatter to the authoritative output across every vendored WASIp2 package, catching parse and format drift automatically.
