Keeping `kind: "select"` for a namespaced definition was a silent downgrade
hazard: released readers drop unknown fields and resolve a select source at
the root, so a rolled-back worker could refresh a view from a same-name root
table and certify the wrong rows.
Root definitions keep the `select` form byte-for-byte; a namespaced source
is stored as `namespaced_select`, which older readers route to their
existing unrecognized-kind refusal. The reader also refuses a kind that
disagrees with its namespace, since no correct writer produces one. The
Python and Node definition parsers learn the new kind alongside the Rust
core, so every same-version reader agrees.
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.
