Subject: refactor: Shader Asset Integration (Task #24)

Extracted all hardcoded WGSL shaders into external assets. Updated AssetManager to handle shader snippets. Refactored Renderer3D, VisualDebug, and Effects to load shaders via the AssetManager, enabling better shader management and composition.
