0441a9d648 feat: UIModule - Dynamic text updates, documentation restructure, and IIO improvements 
UIModule Enhancements:
- Add ui:set_text topic handler to update widget text dynamically (UILabel support)
- Add example: slider value updates linked label via game module coordination
- Add timestamp logging for IIO latency measurement (T0-T3 tracking)

Documentation Restructure:
- Split UIModule README.md (600+ lines) into focused docs:
  * docs/UI_WIDGETS.md - Widget properties and JSON configuration
  * docs/UI_TOPICS.md - IIO topics reference and usage patterns
  * docs/UI_ARCHITECTURE.md - Threading model, limitations, design principles
- Update CLAUDE.md with clear references to UIModule docs
- Add warning: "READ BEFORE WORKING ON UI" for essential docs

Asset Path Fixes:
- Change test_ui_showcase texture paths from ../../assets to assets/
- Tests now run from project root (./build/tests/test_ui_showcase)
- Add texture loading success/failure logs to TextureLoader and ResourceCache

IIO Performance:
- Re-enable batch flush thread in IntraIOManager (was disabled for debugging)
- Document message latency: ~16ms in single-threaded tests, <1ms with threading
- Clarify intentional architecture: no direct data binding, all via IIO topics

a106c78bc8 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
