The CI job moved from the rust:latest image to the generic node:20-bookworm runner image, which has no Rust toolchain preinstalled. Every run was reinstalling the full toolchain via rustup and compiling cargo-make/cargo-audit from source with cargo install, adding ~10 minutes to every build.

This PR:

Adds ~/.rustup to the cache path so the installed toolchain persists across runs
Skips the rustup install step entirely when rustc is already present (cache hit)
Installs cargo-binstall and uses it to fetch prebuilt cargo-make/cargo-audit binaries instead of compiling them from source

Test plan

CI run on this PR completes noticeably faster than the ~10min baseline, especially on a cache hit (second run)

Speed up CI by caching rustup toolchain and using cargo-binstall

CI / ci (pull_request) Failing after 26s

Cache ~/.rustup so the toolchain isn't reinstalled every run, and
install cargo-make/cargo-audit via cargo-binstall instead of
compiling them from source each time.

Force musl targets for cargo-binstall to avoid GLIBC mismatch

CI / ci (pull_request) Successful in 1m47s

Details

The glibc-linked prebuilt cargo-make binary requires GLIBC 2.39,
newer than what's on the node:20-bookworm image. Musl binaries
are statically linked and avoid the mismatch.
