- Replace window class with cbt::opengl::context - Add buffer resource (VBO, EBO, UBO, SSBO) with move semantics - Add texture resource with format/type enums and filtering - Add descriptor_set for Vulkan-style resource binding - All resources use RAII with proper cleanup

# Targets provided:
|
|
# vulkan::vulkan - The Vulkan library target
|

#
|
|
# Variables set:
|
|
# Vulkan_FOUND - TRUE if Vulkan is available
|
|
# Vulkan_LIBRARIES - The Vulkan library target (Vulkan::Vulkan)
|
|
# Vulkan_INCLUDE_DIR - Include directory for Vulkan headers
|
|
# Vulkan_VERSION - Version of the found Vulkan SDK
