Replace legacy download-bonsai-only steps with apply-profile and
bootstrap-stack; note mini CPU vs mid/gaming Vulkan.

+**Compose GPU notes (mid / gaming)**
 - Keep `devices`/`group_add` only in `docker-compose.override.yml` (not also in the main file).
 - Use **numeric GIDs** for `group_add`, not names (`video`/`render` fail inside the image). Or omit `group_add` if `/dev/dri` is mode `0666`.
+- **mini** uses CPU (`BONSAI_NGL=0`) — no GPU devices required.
