Description: ZipProvider threw ERR_METHOD_NOT_IMPLEMENTED for readdir() with { recursive: true }, although an archive already stores every member under its full path, so a recursive listing is the same scan of the entry names as a flat one, keeping the whole path below the directory instead of only its first segment. List every member below the directory, and every directory their paths pass through, whether the archive holds an entry for it or only implies it. Names are relative to the listed directory and joined with /, as MemoryProvider returns them, so VirtualFileSystem reports the right parentPath for each Dirent. A name that is both a member and a directory is listed once, as a directory, as a flat listing already did. The entries are now collected in a map rather than looked up in an array, so listing a directory no longer takes time quadratic in the number of its children.
