Repo stored the repos directory as its base, so runs_base() resolved
to repos/runs/<repo>/ instead of runs/<repo>/. Replaced the
repos_dir field with quire_root — path() constructs the repos path
from the root, and runs_base() uses the root directly. Derived from
the repos_base parent in both constructors.
