Greptile Summary

Adds renderer_type field to CameraCfg allowing Hydra-based runtime selection of renderer backend (RTX vs. Warp). Implements resolution logic in TiledCamera._get_effective_renderer_cfg() to convert string renderer type to concrete config objects.

Key changes:

• New renderer_type field with Literal type hints ("rtx" | "warp_renderer")
• Comprehensive Hydra documentation with override path examples
• Runtime renderer resolution in _get_effective_renderer_cfg() method

Issue found:

• Missing error handling when isaaclab_newton package is unavailable with renderer_type="warp_renderer" (will raise unhelpful ImportError)

Confidence Score: 3/5

• Safe to merge after addressing import error handling for missing isaaclab_newton package
• Score reflects well-documented feature with good design, but missing graceful error handling for optional dependency could cause confusing runtime errors for users
• source/isaaclab/isaaclab/sensors/camera/tiled_camera.py needs error handling for ImportError

missing error handling if isaaclab_newton not installed—wrap in try/except to raise helpful message like visualizer_cfg.py does for Newton visualizers (lines 88-92)
