/**
 * Cross-platform single-binary compile.
 *
 * Run:  bun run scripts/build-binaries.ts
 * Output:  dist/bin/claudemesh-{darwin,linux,windows}-{x64,arm64}{.exe}
 *
 * Each binary bundles the CLI + Bun runtime, no Node required.
 * Current caveat: native deps like libsodium-wrappers ship as JS+wasm
 * so they work. `ws` falls back to its JS polyfill when uws isn't present.
 *
 * Intended for CI — GitHub Releases publish → install.sh / Homebrew
 * pull the right tarball per platform.
