memory_merge
Combine two memories into one by merging content and metadata from a source memory into a target memory, then deleting the source.
Instructions
Merge source memory into target, then delete source.
Combines two memories into one, preserving content and metadata.
Args: source_id: Memory ID to merge from (will be deleted) target_id: Memory ID to merge into (will be updated) merge_strategy: How to combine content: - "append": Append source content to target (default) - "prepend": Prepend source content to target - "replace": Replace target content with source
Returns: Updated target memory and deletion confirmation
