Module sqlquery 

SQL-on-FHIR v2 $sqlquery-run engine.

Pure execution logic: parse a SQLQuery Library, materialize its depends-on ViewDefinitions into an in-memory SQLite database, bind Library.parameter values to the SQL, run the user query, and format the rows.

The REST handler in helios-rest wires this to storage (resolving Library / ViewDefinition resources and supplying RowStreams from the wired SofRunner); this module contains no storage or HTTP concerns.
