disko and nixos-raspberrypi become direct root inputs - their integrations, like zen's, were one mkDefault handing a pin over - and drowse and modular-skills leave entirely, having no consumer in the tree. Evaluating eva-00 for the first time since ironclaw moved into ai/ surfaced a latent gap: the host builds its own pkgs through nixos-raspberrypi's nixosSystem and adds the self overlay explicitly, so ironclaw's rust-bin argument needs the rust overlay added in the same place. Locks ride to the slimmed framework. Signed-off-by: Niclas Overby <niclas@overby.me>
