feat(nodejs): materialized view bindings

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.

+### createMaterializedView()
+
+```ts
+abstract createMaterializedView(
+   name,

+```
+
+Define a materialized view named `name` over the table `source`.
+
+The view is created empty, with the query recorded in its schema
+metadata; `view.refresh()` computes the rows. The view is a normal
+table: it can be queried, indexed and searched, and it appears in
+`tableNames`. The source table must have stable row ids (create it with
+the `newTableEnableStableRowIds` storage option); they keep the view's
+provenance valid across source compactions and cannot be enabled after
+a table exists. Local databases only.
+
+#### Parameters

+
+# Class: MaterializedView
+
+A handle on a materialized view: its table plus its definition.
+
+Obtained from [Connection#createMaterializedView](Connection.md#creatematerializedview) or
+[Connection#openMaterializedView](Connection.md#openmaterializedview). The view is a normal table --
+queries, indexes and search all apply through [MaterializedView#table](MaterializedView.md#table)
+-- whose contents are maintained by [MaterializedView#refresh](MaterializedView.md#refresh).
+
+## Constructors
+
+### new MaterializedView()
+
+```ts
+new MaterializedView(table): MaterializedView
+```
+
+#### Parameters
+
+* **table**: [`Table`](Table.md)
+
+#### Returns
+
+[`MaterializedView`](MaterializedView.md)
+
+## Accessors
+
+### name
+
+```ts
+get name(): string
+```
+
+#### Returns
+
+`string`
+
+## Methods
+
+### definition()
+
+```ts
+definition(): Promise<MaterializedViewDefinition>
+```
+
+The query that defines the view, read from its stored schema.
+
+#### Returns
+
+`Promise`&lt;[`MaterializedViewDefinition`](../interfaces/MaterializedViewDefinition.md)&gt;
+
+***
+
+### refresh()
+
+```ts
+refresh(options?): Promise<RefreshMaterializedViewResult>
+```
+
+Recompute the view from its source.
+
+The refresh is incremental when the source's changes can be reconciled
+into the view -- rows added, changed or removed since the last one --
+and otherwise rebuilds. `full` forces a rebuild; `sourceVersion`
+refreshes to that source version instead of the latest.
+
+Concurrent refreshes of one view do not duplicate its rows. Two that
+plan the same source rows conflict on commit, and the loser throws
+rather than writing them a second time.
+
+#### Parameters
+
+* **options?**
+
+* **options.full?**: `boolean`
+
+* **options.sourceVersion?**: `number`
+
+#### Returns
+
+`Promise`&lt;[`RefreshMaterializedViewResult`](../interfaces/RefreshMaterializedViewResult.md)&gt;
