Adds a declarative 8 GB swapfile at /var/lib/swapfile.

systemd-oomd warned about missing swap. 31 GB RAM is enough for typical ham shack workload, but giving the kernel somewhere to spill cold pages under true memory pressure removes the warning and improves resilience.

XFS supports swapfiles natively; nothing to format manually. NixOS creates and activates the file on next rebuild.

Apply:

sudo nixos-rebuild switch --flake .#hosaka

Verify:

swapon --show
free -h
