/**
 * Release check for the CLI packages. Runs everything a release needs locally and then prints the
 * commands that tag and publish it. It never tags, pushes or publishes.
 *
 *   1. the working tree is clean (no staged, unstaged or untracked changes) and the tags are free
 *   2. npm ci, then the steps the qqq-orb `cli` profile runs: npm run generate with no drift in
 *      packages/ui-api-client/src/schema.ts or packages/core/src/api/operations.ts, build, test;
 *      plus npm run lint (versions, headers) and the TUI's Bun tests and type check (npm run test:tui,
 *      typecheck:tui; the TUI ships inside the binaries)
 *   3. npm pack --dry-run for each published package
 *   4. the single-file binaries with the terminal UI (scripts/build-binaries.mjs; --cli-only leaves it
 *      out) and dist/SHA256SUMS
 *   5. prints the tag, GitHub release and npm publish commands
 *
 * A final (non-prerelease) version also has to pass the readiness gate (scripts/readiness.mjs: parity
 * 100% in both columns, every server finding filed, a CHANGELOG entry, documented commands exist);
 * a prerelease prints the same report as information.
 *
 * Usage: node scripts/release.mjs [--allow-dirty] [--skip-binaries] [--skip-install] [--cli-only]
 *        node scripts/release.mjs --check     only the readiness report (builds first if needed)
 *   --cli-only  build the binaries without the terminal UI (the release artifact bundles it)
