- Create `scripts/setup-swap.sh` to dynamically detect and allocate a 4GB swap file to prevent OOM errors on low-RAM servers. - Integrate the swap check gracefully into the `run.sh` orchestrator flow. - Update `README.md` to document new sudo/disk space prerequisites and the updated deployment steps.
