`POST /memories/{agent_id}/merge`

Collapse two entity-node memories into one.

Live edges incident to ``duplicate_id`` are repointed at ``primary_id``;
the duplicate is soft-marked via ``merged_into``; an ``IS_DUPLICATE_OF``
audit edge is written for traceability. Both nodes must already live in
the requested user+agent scope.

## Authentication

- `HTTPBearer`, http, header `Authorization`

## Path parameters

- `agent_id` (`merge_memories.path.agent_id`; string, required)

## Request body

_Required._

- `primary_id` (`merge_memories.primary_id`; string, required) — UUID of the entity node to keep.
- `duplicate_id` (`merge_memories.duplicate_id`; string, required) — UUID of the entity node to fold into primary.
- `graph_id` (`merge_memories.graph_id`; any of, optional) — Optional. Merge within a shared namespace instead of the user's own memory. Requires a service token; the agent_id path segment is ignored.
