feat(systems): Add swap configuration to multiple hosts
Add swapfile configurations to improve memory management: - athena, demeter (Raspberry Pi): 2GB swap - aion, rhea, kyushu: 8GB swap Swapfiles are automatically created and managed by NixOS without requiring manual partitioning or reinstallation. Signed-off-by: Vincent Demeester <vincent@sbr.pm>
