…torage layer Extends MetadataStorage trait with get_observations, get_payloads, get_direct_descendants_page, and get_group_tree_bfs methods. Adds a group_children sled tree for indexing parent-child relationships at write time, enabling efficient group tree traversal. Replaces offset/limit pagination with UUIDv7 cursor-based page tokens in the observations list API. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
