Subject: [PATCH] fix(ci): disable rust-cache bin caching to unbreak macOS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Swatinem/rust-cache's default cache-clean step poisons ~/.cargo/bin
under rustup 1.28's multicall binary layout — `cargo` ends up restored
as `rustup-init`, breaking `maturin`'s `cargo metadata` call on
macos-latest. Set cache-bin: false and bump prefix-key to evict the
existing poisoned caches.
