Older cached images still contain a literal /home/user/{{WORKSPACE_NAME}}
directory baked in by the previous Dockerfile generation. Even though new
images no longer create it, existing images leave the placeholder folder
alongside the real repo-named mount.
- Add entrypoint cleanup that removes /{{WORKSPACE_NAME}} if it
exists before creating the real workspace target and /workspace symlink
- Update unit tests to assert the stale placeholder removal
