feat: Retained mode rendering for UIModule
...
Implement retained mode rendering system to reduce IIO message traffic.
Widgets now register render entries that persist across frames and only
publish updates when visual state changes.
Core changes:
- UIWidget: Add dirty flags and render ID tracking
- UIRenderer: Add retained mode API (registerEntry, updateRect, updateText, updateSprite)
- SceneCollector: Add persistent sprite/text storage with add/update/remove handlers
- IIO protocol: New topics (render:sprite:add/update/remove, render:text:add/update/remove)
Widget migrations:
- UIPanel, UIButton, UILabel, UICheckbox, UISlider
- UIProgressBar, UITextInput, UIImage, UIScrollPanel
Documentation:
- docs/UI_RENDERING.md: Retained mode architecture
- modules/UIModule/README.md: Rendering modes section
- docs/DEVELOPER_GUIDE.md: Updated IIO topics
Performance: Reduces message traffic by 85-97% for static/mostly-static UIs

fix: UIModule button interaction + JsonDataNode array children support
...
- Fix JsonDataNode::getChildReadOnly() to handle JSON array access by numeric index
- Fix test_ui_showcase to use JSON array for children (matching test_single_button pattern)
- Add visual test files: test_single_button, test_ui_showcase, test_sprite_debug
- Clean up debug logging from SpritePass, SceneCollector, UIButton, BgfxDevice
The root cause was that UITree couldn't access array children in JSON layouts.
UIButton hover/click now works correctly in both test files.
