sceKernelMkdir checked that the parent of the resolved path exists, but for "dir/" std::filesystem::path reports "dir" itself as the parent, so the call failed with ENOENT and created nothing, while FreeBSD's mkdir (and the POSIX mkdir export) accept it. Strip trailing separators first, and report ENOTDIR when the parent exists but is not a directory.
