# Functions
DeleteAllNamespaces uses WalkNamespaces to delete all namespaces, waiting for deletion to complete before returning.
GetNamespaceIDPaths does a namespace list and extracts the resulting paths and namespace IDs, returning a map from namespace ID to path.
PollDeleteNamespace issues a namespace delete request and waits for it to complete (since namespace deletes are asynchronous), at least until ctx expires.
WalkNamespaces does recursive namespace list commands to discover the complete namespace hierarchy.
# Constants
RootNamespaceID is the ID of the root namespace.
RootNamespacePath is the path of the root namespace.
# Variables
ErrNotFound is returned by funcs in this package when something isn't found, instead of returning (nil, nil).
