When API runs in Docker with named volume instance_data:/data/instances,
generated docker-compose.yml files use bind mounts like
/data/instances/.../repo-clone:/workspace. Docker resolves bind mounts
on the host filesystem, not in named volumes, so containers see empty
directories.
By mounting /data/instances as a host bind mount, both the API and
generated tool containers access the same host path.
Git branch -a --format=%(refname:short) returns remote branches as
'origin/branch-name', not 'remotes/origin/branch-name'. The code was
only filtering 'remotes/' prefix, causing clone to fail with branch
names like 'origin/feat/foo'.
Now properly detects remote names using 'git remote' and strips the
remote prefix (e.g., 'origin/') from branch names.
