Module writer 

Msgpack scalar writers for constructing response messages, aggregate results, projections, and other output data — all in raw msgpack without intermediary types.

These are the building blocks for zero-serialization response construction. Follow the timeseries ingest pattern: SqlValue → row_to_msgpack() at ingress, raw msgpack throughout, msgpack_to_json_string() at outermost pgwire/HTTP layer.
