/**
* snapshotPipeline — composes `loadSnapshot` + `writeSnapshot` into a
* `MemoryPipeline` ready to be mounted by `defineMemory({ type: CAUSAL })`.
*
* READ : LoadSnapshot — embed query → search → project → format
* WRITE : WriteSnapshot — embed query → store as MemoryEntry<SnapshotEntry>
*
* The pipeline emits the same `agentfootprint.context.injected` event
* (with `source: 'memory'`) as every other memory flavor, so Lens
* shows Causal injections as memory chips alongside Episodic /
* Semantic / Narrative without special UI.
