Subject: [PATCH] ci: switch to Swatinem/rust-cache to fix macOS build (#90)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Caching ~/.cargo/bin/ via actions/cache@v4 was poisoning the cargo
shim on macOS runners — restored cargo resolved to rustup-init and
failed with "unexpected argument 'build' found". Swatinem/rust-cache
skips that directory and handles target/ pruning + key derivation.
