Minimal dinit + Nix Linux system with per-user overlay stores. Renamed from DiNix, restructured flake architecture: - Distro flake = build tooling (lib.minixSystem, homeModules, disk images) - Machine flake = per-device config at /etc/minix/ (mutable, first-boot-only) - User HM config = independent, scaffolded via minix-home init Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
