/**
 * Publish the CLI to npm. Runs in the Release workflow via npm Trusted Publishing (OIDC),
 * so no npm token is needed. Expects binaries in dist-exe (`bun run build:single-exe:all`).
 *
 * 1. Prepare npm packages from dist-exe
 * 2. Publish platform packages
 * 3. Wait until every platform package is live on npm
 * 4. Publish the main package
 *
 * Packages already on npm are skipped, so a failed run can simply be re-run.
