Renderer / preview: - Switch the preview/display readback format from F16 to packed 10-bit RGBA (PixelFormat::U10) to halve GPU->CPU/IPC bandwidth while keeping 10-bit panel precision. - Add U10 support to VideoParams, FFmpeg/OIIO/OCIO utility mappings, OpenGL (GL_RGB10_A2), Vulkan (VK_FORMAT_A2B10G10R10_UNORM_PACK32), and plugin bit-depth lookups. - Update preview autocacher comment to reflect the new behavior. OCIO LUT tests: - Add four E2E-style ColorLutNode gtests that drive a SolidGenerator -> OCIOLutNode graph through NodeTraverser and compare resulting pixels on the CPU. They cover forward/inverse transforms and verify that switching LUT direction and LUT file updates both the processor and the output pixels. Cleanup: - Remove a leftover SolidGenerator::Value debug fprintf. - Capture render worker stderr in RenderWorkerFootageTest for better diagnostics.
