Grid.__init__() now auto-creates a GridView that shares the Grid's data via aliasing shared_ptr. This enables the Grid/GridView split: - PyUIGridObject gains a `view` member (shared_ptr<UIGridView>) - Grid.view property exposes the auto-created GridView (read-only) - Rendering property setters (center_x/y, zoom, camera_rotation, x, y, w, h) sync changes to the view automatically - Grid still works as UIDrawable in scenes (no substitution) — backward compatible with all existing code and subclasses - GridView.grid returns the original Grid with identity preservation - Explicit GridViews (created by user) are independent of Grid's own rendering properties Addresses #252. All 260 tests pass, no breaking changes. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
