/**
 * @module @nhtio/adk/batteries/vector/typesense
 *
 * Typesense adapter. Each collection is a Typesense collection with a `float[]` vector field
 * (native `vector_query` KNN). Metadata is stored as a JSON string field and filtered with
 * the neutral filter tree's JS reference evaluator for exact cross-adapter parity (Typesense
 * filter_by requires per-field schema declaration, which the neutral metadata model doesn't
 * have). Document + id are plain fields.
 *
 * Driver: `typesense` (pure JS).
