What

Adds the missing device-table entry for the Adreno 831:

GPUId(chip_id=0x44050100, name="Adreno (TM) 831"), # KGSL

attached to the Adreno 830 entry (GPUId(chip_id=0x44050001, name="Adreno (TM) 830")), guarded so it becomes a no-op once Mesa upstream carries the part.

Why

Mesa upstream freedreno_devices.py does not currently index the Adreno 831 chip ID (0x44050100), causing Turnip to reject device creation with VK_ERROR_INCOMPATIBLE_DRIVER:

TU: error: .../tu_device.cc: device (chip_id = 44050100) is unsupported (VK_ERROR_INCOMPATIBLE_DRIVER)

Adding this entry allows Turnip to initialize on Adreno 831 devices such as the XREAL AURA.

Tested on

• Hardware: XREAL AURA (Adreno 831 GPU 0x44050100, Android XR)
• Tested in DroidDeck experimental Android XR runtime (feat: add experimental Android XR support DroidDeck#1377):
  • SteamVR and OpenXR stereo frame presentation active at 72 Hz
  • Head tracking and 3D scenes rendering via Turnip

Scope

• Additive: only affects devices reporting 0x44050100.
• Guarded by if '0x44050100' not in Path(DEVICES).read_text(): so it is safely skipped once Mesa main carries the entry upstream.
