refactor: deps desde el tarball oficial (flujo doc oficial)

- Nuevo modo --extract en openvino_logic.sh: extrae el tarball con el trap de limpieza de extraccion parcial (O6 reubicado aqui)
- --install queda en politica replace + mv + symlink (la extraccion ya sucedio en --extract)
- main.sh reordena: download -> extract -> deps (del tarball, con validacion temprana del path install_dependencies/) -> install
- deps/ eliminado (357 lineas de fork): upstream incluye debian13+ubuntu26 nativamente; el script del tarball va siempre version-matched
