darmanandClaude Opus 5 2abd842e97 terra: tome, rootless podman for GPU containers, direnv, kicad
- install tome from pkgs/tome.nix, built against the re-added flake input
- import services/containers.nix and put darman in `render`/`video`:
  /dev/dri/renderD128 is root:render 0660, so a rootless container can only
  reach the GPU if the host user is in the group. Needed by the Vulkan
  whisper.cpp/llama.cpp containers in content-trigger-scanner.
- point DOCKER_HOST at the podman *user* socket and add docker-compose.
  dockerCompat gives a `docker` CLI shim, but compose v2 is its own binary
  talking to a socket, and rootless podman's socket is the user one under
  /run/user/1000 — not root's /var/run/docker.sock.
- direnv + nix-direnv, so per-repo devShells load in the shell and in Rider
  via its direnv plugin, instead of hand-wiring a toolbox SDK per repo
- kicad as a flatpak, alongside the other flatpak desktop apps
