SQL Result Row Normalizer (engine-sql/normalize.ts)

Normalizes heterogeneous SQL query results from different database drivers into a uniform schema. Use this to ensure consistent data types across multiple database backends in your application.

/**
 * Row normalizer for engine-sql results (refactor wave 1, A5).
 *
 * PGLite and postgres.js decode some column types differently (int8 as
 * number vs string, vector as text, timestamps as string on text projections).
 * A statement that needs a uniform shape declares each column's kind ONCE, at
 * module scope; `compileRowNormalizer` returns a function that converts only
 * the declared columns and leaves every other column as the driver returned
 * it. The declared kind picks the conversion, never the value's runtime type.
 * `test/engine-sql-normalize.test.ts` pins each kind on both engines.
