//! Main WGPU renderer implementation
//!
//! This module contains the main WgpuRenderer struct and its implementation,
//! following the pattern from imgui_impl_wgpu.cpp
//!
//! Managed texture flow (Dear ImGui 1.92+):
//! - `Context::render(renderer.renderer_consumer()?)` returns a Context-borrowed `PendingFrame`.
//! - WGPU consumes every managed-texture request before producing a drawable `ReconciledFrame`.
//! - WGPU stores managed GPU resources by pointer-free `SnapshotTextureId`.
//! - Legacy application textures continue to use `TextureId` without entering this protocol.
