Subject: [PATCH] ci: disable cache-bin in setup-rust-toolchain

Avoid restoring a stale rustup proxy binary from cache over the freshly
installed one. The new Homebrew rustup formula ships a wrapper that drops
argv[0], breaking cargo/rustc multiplex dispatch; once a poisoned
~/.cargo/bin/ lands in the GHA cache it re-poisons every later run on
that key. We don't cargo-install any tools, so the cache is pure risk.
