The keep-alive stops the default 5-minute idle unload from adding a reload stall to every resumed session on a single-user workstation. Update flake to get newer packages.

Old configuration.nix/programs.nix removed. - profiles/: coarse opt-in bundles (desktop, dev, apps). kusanagi imports all three and stays byte-for-byte identical to the running system. - machines/kusanagi/: all workstation-only config (ROCm, Scarlett audio, optical-disc archiving, NAS mounts, kavita/immich/ollama); hardware config moved here unchanged. User stays 'henz'. - machines/enzo/: new laptop. Declarative LUKS+btrfs via disko (LVM-on-LUKS, TPM2+PIN unlock, zram + encrypted swap for suspend-then-hibernate); its own minimal niri desktop with playback-only audio (no rtkit/jack); user 'hwebs'.
