Render an interactive Scene Graph in the Settings panel using @visual-json/react. Introduces SceneNode/SceneGraphNode types and buildSceneGraphValue to build a tree (handles missing nodes and cycles), and adds handlers to block drag/drop/context/delete mutations inside the viewer. Adds @visual-json/react to apps/editor package.json and updates the dev script to forbid .env.local and source the root .env instead. Also adds a persistence migration in use-scene to preserve existing nodes and rootNodeIds when the persist version changes.
Replaces usage of the Asset type with AssetInput across editor components and hooks for consistency with core types. Adds default dimensions fallback for asset placement logic. Refactors UI primitives (button, sidebar, opacity control) to support forwarding refs and asChild prop, and updates imports for primitives. Updates Radix UI dependencies in package.json and bun.lock.
