Refactored VK layer handling by changing return type of `use_layers` to `Vec<CString>`, adjusting subsequent usage of layers. Implemented `Display` for `VkPhysicalDevice` for better logging. Enhanced application initialization with detailed window attributes. Transitioned to using `log::info` for consistent logging.
