Robot V4L2 release

This directory is the extracted OmniSocketGo_robot-20260808 package. The runtime path opens the selected /dev/video* node directly and performs the existing MJPEG/KCP transport pipeline.

Before starting:

cd OmniSocketGo_robot
./check-robot-lan.sh

If a camera is reported busy, inspect lsof/fuser and stop the specific camera service or process first. Start this release with:

./start-robot-lan.sh

Build on the ARM64 robot with the included Makefile; do not reuse host binaries. The scripts/dev/*.env file is a template. Keep machine-specific values in an ignored robot-remote.env.local.
