## Title

    Proposed fix: [Rust/cargo] 'error: linker `cc` not found' on fresh Linux image/container — rustup installs no C linker; install build-essential/gcc/clang

## Body

    Recommended action: Install a C toolchain: build-essential on Debian/Ubuntu (or distro GCC/Clang), `xcode-select --install` on macOS, Visual Studio build tools on Windows MSVC.
    
    Option: Install a C compiler/linker [evidence: official_recommended_action]
    Applies when: Linux/macOS minimal environments
    Steps:
    1. Debian/Ubuntu: apt-get install -y build-essential
    2. Other Linux: install gcc or clang per distro docs
    3. macOS: xcode-select --install
    4. Re-run cargo build
    Expected: Linking succeeds
