* fix(uninstall): keep a managed cache namespace whole when it holds a caller-selected Kuna cache purge --purge-data reported a REA_KUNA_CACHE_DIR selection below the default Kuna cache as retained, then removed it together with its parent namespace. A namespace that contains the selection is now retained and reported, so the retained report is true. Fixes #7344 * fix(uninstall): also keep a namespace equal to, or reached by symlink traversal from, the selected Kuna cache Compare the namespace and the selection with the same normalization, treat an equal path as contained, and resolve existing paths before planning so a symbolic link followed by .. is judged by where it leads. * fix(uninstall): judge a selection with parent traversal where the filesystem resolves it Collapsing .. lexically contradicts the existing rule that parent traversal after a symbolic link leads elsewhere, and broke the retained-through-symlink-traversal test. Compare spellings without .. directly and resolve existing paths for the rest, so the symlink-parent case still purges the default cache while a selection that resolves into a managed namespace is retained. * fix(uninstall): keep a namespace whole when the selection's location is unknown A realpath failure other than ENOENT/ENOTDIR (for example EACCES under an inaccessible parent) no longer counts as "absent". Each namespace that may contain the caller-selected Kuna cache is retained instead of purged.
