- Replaced the slim artifacts-only image with a full pi-base image (python + bun + rustup + natives + omp_rpc + omp shim).
- Moved robomp Dockerfile to repo root as Dockerfile.robomp, extending pi-base instead of copying from a scratch artifacts image.
- Renamed PI_ARTIFACTS_IMAGE to PI_BASE and updated all npm scripts and compose config accordingly.
- Split .dockerignore into per-Dockerfile shadows (Dockerfile.dockerignore, Dockerfile.robomp.dockerignore).
