 * Freshness check for project-root.generated.cjs.
 *
 * Regenerates the expected CJS content in-memory (without writing to disk) and
 * compares it to the committed file. Exits 0 if they match, 1 if stale.
 *
 * Uses Phase 3's cleaner pattern: imports buildProjectRootCjs() from the
 * generator directly rather than duplicating the build logic.
 *
 * Run: node sdk/scripts/check-project-root-fresh.mjs
 * (Requires sdk/dist to be built first — `npm run build` in sdk/.)
