详细描述

Read-only snapshot of WebGPU adapter/device limits and surface capabilities, queried once after device creation.

Mirrors the capability-probe pattern of vk-bootstrap (PhysicalDevice/Device queries) so feature-gated paths (MSAA sample count, formats, bind-group budget) can reject infeasible requests before issuing a GPU call, instead of guessing and crashing at validation time.
