Subject: [PATCH] Update: OpenVINO 2026.4.0 + NEO 26.35.39758.10 + fixes de
 robustez y Mesa

- OpenVINO Runtime 2026.4.0.22959.99c81491cc3 (BASE_URL packages/2026.4)
- NEO 26.35.39758.10 + IGC 2.41.5+22716 (6 paquetes de produccion, sin dbgsym/-devel)
- Mesa >= 25.2 en Debian 13: mesa-libgallium sustituye mesa-va-drivers/mesa-vdpau-drivers (Rompe < 25.2.8-3)
- INSTALL_DIR derivado de la version (/opt/intel/openvino_2026.4.0) con politica replace y symlink estable
- rm -rf cubre symlink O directorio real en la limpieza previa
- deps/: set -euo pipefail + guard ${1:-} (sin abortos esporios)
- DRY flags/GPU: read -r con guard EOF, deteccion GPU sin SIGPIPE, trap EXIT en modulos, GPU_PRESENT como comparacion
- .gitignore: artefactos de instalacion fuera del repo

 **Core Runtime & Libraries:**
-*   **OpenVINO Toolkit 2026.0:** The complete runtime package is downloaded from the official OpenVINO repository (`https://storage.openvinotoolkit.org/repositories/openvino/packages/2026.0/linux`) and installed under `/opt/intel/openvino_2026`. It is the same version used in llama.cpp in its builds.
