v4: the devcontainer builds and starts again — the docker-outside-of-docker feature failed to install, since the base image is now Debian trixie, where its default moby option isn't supported; it now installs Docker's own packages ("moby": false). Every service of the compose project was also built under one image name, gerbeur-dev, the workspace with the features and the others without, so whichever finished last took the name and the workspace could lose its docker CLI; each service now gets its own image, built from the same cache.

Checked with the devcontainer CLI's up: the image builds, install exits 0, gerbeur and musique answer on :3000, :3001, :8000 and :8001 (openid-configuration included), and docker ps works as node in the workspace.
