v1.22.0: la IA del equipo (máscara de sujeto en la tarjeta NVIDIA)

La máscara de «Sujeto» y «Fondo» del editor de revelado de Labstream OS la busca
la app en la tarjeta del equipo, no el navegador (src-tauri/src/ia/):

- Tres comandos para la página, permitidos solo para el origen de la app (manifiesto
  en build.rs + capabilities): ia_estado (¿hay NVIDIA?, ¿está bajado?, cuánto
  falta), ia_preparar (baja lo que falte con eventos ia-progreso y abre el modelo)
  e ia_sujeto (RGBA en binario → [ancho][alto][un byte por punto]).
- Motor: ONNX Runtime 1.24.4 con DirectML (crate ort 2.0.0-rc.14, load-dynamic,
  api-24): nada se enlaza al compilar; las DLL se bajan de NuGet la primera vez y
  DirectML.dll se carga por su ruta antes que onnxruntime.dll. Sin fundir el grafo
  (fundido, el HR no cabía en 16 GB) y sin seguir en la CPU si la tarjeta falla.
- Modelo: BiRefNet general en media precisión, del servidor de la app con la
  sesión de la pestaña (cookies de WebView2 leídas en el comando asíncrono).
- Todo fijado por huella SHA-256; los .nupkg se sacan por ruta exacta (DirectML trae
  también las DLL de Xbox y de depurar con el mismo nombre).
- ¿Hay NVIDIA?: los adaptadores de DXGI, sin cargar nada de la IA.
- El modelo se suelta de la tarjeta a los 2 min sin uso; si la tarjeta falla, se
  suelta y se abre de nuevo la próxima vez. Todo va a salud.log.

Medido en una RTX 5080: 0,3 s por foto (1,4 s la primera; el navegador tarda
2,5–3 s) y el mismo borde que el modelo original en la CPU. El HR (2048 px,
matting) se probó y se descartó: 14–15 GB de la tarjeta y de 6 a 45 s por foto.

Pruebas nuevas: zip por ruta exacta, entrada igual a la del navegador, salida y
respuesta; y una de punta a punta en la tarjeta (ignorada en CI).
