Add TextSharpnessManager for crisp text rendering at all zoom levels: - Discrete zoom buckets (0.5–3x) avoid texture churn on small zoom changes - Initial bucket applied to all items on setup and newly created items via SceneManager.onItemCreated callback (fixes blurry-on-load) - Visibility check uses getItemWorldBounds for correct grouped item coords - TextSprite/StickySprite gain setZoomBucket() for resolution control Remove fontSize +/- controls from contextual toolbar — font size is now controlled purely through direct manipulation (resize → bake).
