v0.6.5

Fixed

• memory_search no longer crashes on metadata-only queries such as task_id:TASK-123 or task_id:<relay-uuid>; total_found is now populated correctly for index-backed filter-only results

Changed

• memory_search tool description now documents that task_id, agent_id, and relay_session_id can be passed either as explicit parameters or as query filters, and clarifies accepted task_id formats
