/**
 * Renders the sbatch script that launches a Nebula client-server inside a job.
 *
 * The rendered job:
 *  - re-invokes this very Nebula install (same node binary + entry) with --client
 *    from the same working directory (all visible on the shared filesystem),
 *  - points it at the login-node main server,
 *  - carries a one-time allocation token so the main server can correlate the
 *    resulting registration back to this allocation.
 *
 * The client spawns its kernels locally (ZeroMQ on 127.0.0.1 on the compute
 * node); nothing here touches the kernel transport.
