Subject: [PATCH] feat: menu CLI minimalista (pure-bash, cero dependencias)

- core/menu.sh: show_menu() con navegacion ANSI pura (read -sn1 + clear via printf ANSI), flechas up/down + Enter, atajo numerico 1-5/0, q/ESC salir, guard EOF
- main.sh: menu como entrada por defecto (los flags --yes/--no-gpu la bypassan); despacho sin logica de negocio (MODE: full/neo/openvino + subcomandos doctor/uninstall)
- Control de flujo: MODE!=openvino salta NEO; MODE=neo finaliza tras NEO (sin abrir OpenVINO)
- Verificado: tecla 4 -> doctor completo, q/ESC/EOF -> salida limpia, opcion 2 sin root -> error de privilegios
