Implemented: - Advertise Voxy-required DirectVulkan extensions without raising the reported OpenGL version. - Add DirectVulkan compute, indirect draw count, DSA, readback, and buffer state paths needed by Voxy. Fixed: - Enable Vulkan shaderInt64 and drawIndirectFirstInstance so Voxy baseInstance-driven LOD draws address the correct section data. - Fix DirectVulkan synchronization, framebuffer, texture readback, and shader interface handling used by Voxy and Minecraft screenshots. Tests: - Add MG_Test coverage for DirectVulkan extension advertising, DSA buffer/texture/framebuffer/vertex-array behavior, persistent mapped readback, and shader/program paths.
