Function wrappers_semantically_equal 

fn wrappers_semantically_equal(a: &str, b: &str) -> bool

A match requires ( + one or more non-()/non-newline chars + .rs: + ASCII digits + : + ASCII digits + ). Malformed or non-.rs patterns are left untouched.

Host-only: the sole caller is write_r_wrappers_to_file, gated off on wasm32 (the wrapper-gen pass doesn’t run there).
