Classify RX 6700 XT WSL2 path as unverified (#1752)

Browse Source 
Closes #1716.\n\nDefines supported, best-effort override, unverified, and unsupported architecture evidence; marks RX 6700 XT/gfx1031 over WSL2 ROCDXG as unverified; and requires routing, utilization, and CPU-fallback evidence before claiming acceleration.

#### WSL2 architecture compatibility matrix
VoiceStudio classifies the architecture result separately from device-node
visibility. `/dev/dxg` alone is not proof of acceleration; a supported claim
also needs the runtime probe, application routing, a completed workload, and
GPU-utilization evidence.
| Classification | Evidence required | VoiceStudio behavior |
|---|---|---|
| **Supported** | The native GFX tag is in the shipped PyTorch architecture list, and the named hardware has a published successful workload with GPU-utilization evidence. | Report the measured provider and device from Settings and diagnostics. |
| **Best-effort override** | The native tag is absent, a mapped target is present in the PyTorch build, and `HSA_OVERRIDE_GFX_VERSION` is applied. No hardware validation is implied. | Attempt the mapped kernels; capture execution evidence and treat failures as unsupported for that host. |
| **Unverified** | The bridge or override is configured, but no published end-to-end result exists for the named card and stack. | Do not advertise the card as supported; run the checks below before relying on it. |
| **Unsupported** | Neither the native tag nor a usable mapped target is present, or the runtime/workload rejects the device. | Use an intentional CPU route or a different supported accelerator. |
| Hardware / architecture | Current classification | Detail |
|---|---|---|
| AMD Radeon RX 6700 XT / `gfx1031` through WSL2 ROCDXG | **Unverified** | VoiceStudio can map `gfx1031` to `gfx1030` when that target exists in the PyTorch build, but no RX 6700 XT end-to-end validation has been published. |
For an RX 6700 XT result to move out of **Unverified**, record the Windows AMD
driver, WSL kernel/distribution, image and ROCDXG/ROCm versions,
`torch.version.hip`, device name/count and compiled architecture list, effective
HSA override, `rocminfo`, VoiceStudio self-check and engine-routing output, and
one successful PyTorch TTS and ASR workload with utilization plus cold/warm
latency. Record whether either workload fell back to CPU and, when it did, the
CPU fallback stage and reason reported by VoiceStudio. A CPU-only completion
does not qualify as successful GPU validation.
The same flags work with **Podman** (`podman run --device /dev/kfd
--device /dev/dri …`); in a **Quadlet** unit that's two `AddDevice=` lines:
