Bounds plugin disk use: installing never removed the version it replaced, so ~/.kandev/plugins/<id>/ accumulated a full copy per install forever (4.2GB on one machine, 3.74GB of it superseded versions). A plugin now keeps its active version plus one rollback target, pruned only once the new version is confirmed running.
