Rust 1.97 makes Rust‑specific symbol mangling the default, tightening build reliability
Rust 1.97 ships Rust‑specific symbol mangling v0 as the stable default, fixing hash‑based generics and reducing custom demangling. Cargo now lets CI deny warnings via a simple env var, and linker output is no longer hidden, making build failures easier to spot. These changes tighten debugging and CI reliability.
