Shader class

A shader Resource that represents a compiled shader program and the uniform data that will be bound to it.

Uniform values are set by string key ('VertexInfo.model', 'Lights.positions[0]', 'someColor') and are automatically packed into GPU buffers using shader reflection for layout.

Samplers are auto-detected at compile time via gpu.UniformSlot.sizeInBytes returning null — no need to declare them separately.
