- No need to keep compatibility with the old evalstone/ subdirectory layout.
- Now simply removes everything except datasets/ and docker/, then clones
the code directly into root.
- Previously the script cloned code into /evalstone/, so after
mounting the host directory to /opt/evalscope the container could not find
bash/run.py and the evalscope package.
- Now the script clones directly into root, preserving existing
datasets/ and docker/ directories.
- Also handles migration from old evalstone/ subdirectory layouts.
