* fix(mcp): keep store receiver bound in scene event operations
appendSceneEvent and listSceneEvents detached the store methods before
invoking them (const append = this.requireStore().appendSceneEvent;
append(options)), so `this` was undefined inside store implementations
that rely on it — SqliteSceneStore.withWriteTransaction in particular.
Every save_scene, create_from_template, and live-sync mutation routed
through the facade failed with "undefined is not an object (evaluating
'this.withWriteTransaction')" even though the SQLite write succeeded.
Invoke the methods on the store instance instead, and add facade-level
regression tests covering both the bound-receiver path and the
stores-without-scene-events fallback.
