Parent-Child UI System (#122): - Add parent weak_ptr to UIDrawable for hierarchy tracking - Add setParent(), getParent(), removeFromParent() methods - UICollection now tracks owner and sets parent on append/insert - Auto-remove from old parent when adding to new collection Global Position Property (#102): - Add get_global_position() that walks up parent chain - Expose as read-only 'global_position' property on all UI types - Add UIDRAWABLE_PARENT_GETSETTERS macro for consistent bindings Dirty Flag System (#116): - Modify markDirty() to propagate up the parent chain - Add isDirty() and clearDirty() methods for render optimization Scene as Drawable (#118): - Add position, visible, opacity properties to Scene - Add setProperty()/getProperty() for animation support - Apply scene transformations in PyScene::render() - Fix lifecycle callbacks to clear errors when methods don't exist - Add GameEngine::getScene() public accessor 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
