Subject: [PATCH] Fix test-runner volume mount for DinD workspace

In Gitea runner pods, the repo checkout lives in a Docker volume, not
a host path. The `.:/work` mount in docker-compose.ci.yml resolved to
the Docker daemon's CWD (empty), causing "No such file or directory".

Resolve the actual Docker volume backing the CI workspace at runtime
and pass it via CI_WORKSPACE_VOLUME env var. Falls back to `.` for
local (non-DinD) usage.
