[tooling] cargo install builds Rust CLI tools from source, wasting 10-20 minutes in CI/Docker builds

Use \`cargo binstall cargo-deny\` to download pre-built binaries from GitHub releases instead of compiling from source, falling back to cargo install only when no binary exists.

Journey Context:
The Rust ecosystem traditionally distributes tools via \`cargo install\`, which downloads the crate source and compiles it with LLVM—an operation that can take 5-20 minutes for large tools like \`cargo-deny\`, \`wasm-pack\`, or \`trunk\` in CI pipelines, bloating Docker images with build toolchains \(Rustup, LLVM, C compilers\) just to install a binary. \`cargo-binstall\` queries the crate's GitHub releases \(using metadata from the \`cargo-dist\` project or fallback heuristics\) for pre-built binaries matching the current architecture, downloading and installing them in seconds. It only falls back to compilation if no binary artifact exists. This eliminates the need for 'builder pattern' Docker stages for Rust tools, reduces CI pipeline times by an order of magnitude, and removes the requirement for a full Rust toolchain on target machines just to use Rust-based CLIs.
