lucannez64andClaude Opus 5.5 40f7a650d1 Report the host GPU name and VRAM from MTLDevice ...

-[MTLDevice name] returned "Darling Indium Device" for every GPU. It now
returns the selected Vulkan device's name in macOS Metal style: the
trailing driver note in brackets and the (R)/(TM) marks are removed, and
NVIDIA names are unchanged. The name is never replaced with another
vendor's. recommendedMaxWorkingSetSize is the device-local heap size on
discrete GPUs and all heaps on integrated/CPU devices, with the old 1 GiB
as fallback. Both are computed once per device.

hasUnifiedMemory stays YES by default: synchronizeResource:/
synchronizeTexture: are missing and Private buffers created with data
abort in Indium, so reporting NO on discrete GPUs would send apps down
unimplemented paths. DARLING_METAL_HOST_UNIFIED_MEMORY=1 opts in to the
GPU-type answer. DARLING_METAL_GPU_NAME and DARLING_METAL_VRAM_MB
override the name and working set.

The cleaning logic lives in private-include/Metal/MTLDeviceInfo.h and is
covered by the host check tools/test-metal-device-info.cpp. Metal now
links indium_private for the Vulkan properties, and the runtime build
script adds Indium's private headers before compiling MTLDevice.mm.
