Else it falls back to cargo build install etc...

Ubuntu docker n rustup multiarch targets
Llvm-mingw64 could autobake for all...

Start with the repository's current GitHub Release Action and Docker/build configuration; the issue names no specific file or test entry point. Clarify whether the scope is cargo-binstall package metadata, fallback installation, or the proposed multi-target release build. Done should be a reproducible release workflow covering the agreed targets and installation path.
