Refactors rendering pipeline with flexible data handling

Removes hardcoded data from render context, allowing more dynamic renderer implementation

Changes include:
- Decoupling data retrieval from render context
- Simplifying renderer interface
- Supporting more flexible data traversal strategies

Prepares for more modular and adaptable rendering approach
