fix(setup): report Kuna cache aliases consistently (#7207) Unify lexical default-cache reports without changing removal authority. Plan selections before deleting managed directories; resolve absolute POSIX paths independently of ambient cwd. Preserve parent traversal, literal backslashes, caller data, and result/removal order.
