Operation to list and filter namespaces in the store.
This dict is mutable — auth handlers can modify namespace (the prefix)
to enforce access scoping (e.g., prepending the user's identity).
StoreListNamespaces()typing.TypedDictPrefix filter for namespaces. Can be None if no prefix was provided.
Auth handlers can modify this to enforce per-user scoping. When None,
handlers should set it to (user_id,) to scope listing to the user's namespaces.
Optional conditions for filtering namespaces.
Maximum depth of namespace hierarchy to return.
Maximum number of namespaces to return.
Number of namespaces to skip for pagination.
