ClayWorkspace Resource Tree

Implement a `ClayWorkspace` backed by a dictionary of resource ids to `Resource` objects. The initial API creates resources and lists a folder's contents; the follow-ups add recursive deletion and moving a resource either to the home level or under another folder id. Requirements Implement a workspace/resource manager with a dictionary mapping resource ids to Resource objects. The initial interface is: class ClayWorkspace: def __init__(self): ... def create_resource(self, resource_name: str, resource_type: ResourceType, parent_folder_id: str): ... def list_resources(self, folder_id: str): ... Follow-ups: Given a resource id, delete that resource and every nested resource below it recursively. Given a resource id and any additional parameters you need, move that resource either to the home level or into another folder referenced by id. Notes Model each resource with at least an id, name, type, parent pointer or parent id, and a collection of child ids for folder resources. create_resource should update both the global id-to-resource dictionary and the parent folder's child collection. Recursive delete must remove descendants from the global dictionary as well as detach the deleted root from its parent. Move semantics need cycle protection: a folder should not be movable into itself or one of its descendants. Clarify whether list_resources returns ids, names, Resource objects, or a stable ordering before coding. Preparation Implement the base class with parent and child pointers, then add delete and move as separate methods without changing the data model. Test root-level creation, nested folders, deleting a folder with multiple descendants, moving a leaf, moving a subtree, invalid parent ids, and self/descendant moves.
