Exposes materialized views to TypeScript: createMaterializedView,
openMaterializedView and listMaterializedViews on Connection, and a
MaterializedView handle carrying the parsed definition and
refresh({full, sourceVersion}), which returns the typed refresh result.
select accepts column names, [alias, expression] pairs, or a record of the
same; the definition reads back off the stored schema, so a reopened handle
needs no side channel. Remote connections surface the core's not-supported
error up front.
The napi crate needed the same recursion-limit raise as the core crate: the
refresh future's type graph overflows the default trait-recursion depth.
