Moves VppRetiler, VaProcPipelineParameterBuffer, and va_check from dmabuf_import.rs into render/vpp_retiler.rs so it can be shared by both the wgpu (Vulkan DMA-BUF) and GLES (EGL DMA-BUF) render paths. No behavioral change. Restores the multi-GPU render node fallback range (renderD128..135) that was narrowed in the original branch.

…tracking GlesRenderer: - Add NV12_RG_FRAG_SRC shader for RG8 UV textures (DMA-BUF import produces GL_RG8 instead of LUMINANCE_ALPHA). - Add Nv12Rg ActiveMode and select the correct program in draw(). - Add GlesRenderPath enum and last_render_path() for observability. - Log render path transitions. GlesDmaBufImporter: - Add EGL DMA-BUF format/modifier query and diagnostic logging. - Add eglGetError resolution and egl_error_name for better error reporting on import failures. - Add VPP retiler integration for incompatible tiling modifiers. - Add query_non_external_modifiers for modifier compatibility checks. audio_backend: demote verbose stream config enumeration to trace.

GTK4 integration for video rendering, using GLArea with native OpenGL. The GLES renderer now supports zero-copy DMA-BUF import via EGL, with automatic VPP retiling when the buffer modifier is incompatible (e.g. Y_TILED from VAAPI decode on Intel MTL, which EGL/iris can handle but needs retiling for per-plane R8/GR88 import).
