Module in_memory 

In-memory brute-force cosine VectorBackend.

No external dependencies and always available (not behind a feature flag). Intended for tests and tiny document sets — O(n·d) per query is fine up to ~10⁴ vectors; beyond that switch to SqliteVecBackend (exact KNN) or UsearchBackend (HNSW ANN).
