Detailed Description

Provides the foundational Shaders class that manages OpenGL shader programs, including compilation of shader units (vertex, fragment, compute, geometry), linking into programs, and runtime uniform setting. This is the base class for specialized shader types (RenderShader, ComputeShader, etc.).

GPU Resource Ownership: * Shaders owns the OpenGL program object (program_id) * Shader units (vertex/fragment/etc.) are owned by derived classes * Resources are deleted in destructor via glDeleteProgram

Architecture: * Pure virtual methods enforce shader type-specific behavior * Derived classes implement shader parsing, compilation, and linking * Uniform cache minimizes redundant glGetUniformLocation calls
