feat(templates): add ROS2 Jazzy visual demo template for QEMU VM testing

Add a minimal robotics demo image template (Ubuntu 24.04 + ROS2 Jazzy)
optimized for running visual demos in a QEMU VM with X11 forwarding.

Includes:
- ROS2 Jazzy core with CycloneDDS middleware
- Turtlesim, rqt_graph, rqt_plot, demo_nodes for visual demos
- xauth + x11-apps for SSH X11 GUI forwarding
- SSH AddressFamily inet fix for QEMU IPv6 socket issue
- IPv6 disabled via sysctl for VM environments
- Pre-configured robot user with sudo access
- AI-searchable metadata for template discovery
- Complete VM setup and demo steps in header comments

+# Robotics AI Suite: Visual Demo Image Template
+# Ubuntu 24.04 LTS + ROS2 Jazzy + Turtlesim + rqt tools
+#
+# Minimal image for running visual ROS2 demos in a QEMU VM.
+# Includes turtlesim, rqt_graph, rqt_plot, and X11 forwarding support.
+#
+# Usage:
+#   sudo ./os-image-composer build -t image-templates/robotics-demo-ubuntu24-x86_64.yml
+#
+# VM prerequisites:
+#   sudo apt install -y qemu-system-x86 ovmf
+#   cp /usr/share/OVMF/OVMF_CODE_4M.fd .
+#   cp /usr/share/OVMF/OVMF_VARS_4M.fd .
+#
+# VM launch:
+#   qemu-system-x86_64 -machine q35 -enable-kvm -cpu host -smp 4 -m 4096 \
+#     -drive if=pflash,format=raw,readonly=on,file=OVMF_CODE_4M.fd \
+#     -drive if=pflash,format=raw,file=OVMF_VARS_4M.fd \
+#     -drive file=robotics-demo-ubuntu24-24.04.raw,format=raw,if=virtio \
+#     -device virtio-net-pci,netdev=net0 \
+#     -netdev user,id=net0,hostfwd=tcp::2222-:22 \
+#     -nographic
+#
+# Connect with X11 forwarding:
+#   ssh -X -p 2222 robot@localhost
+#
+# ROS2 is auto-sourced on login. If needed manually:
+#   source /opt/ros/jazzy/setup.bash
+#
+# Run demos:
+#   # Demo 1: Turtlesim — visual turtle control with arrow keys
+#   ros2 run turtlesim turtlesim_node &
+#   ros2 run turtlesim turtle_teleop_key
+#
+#   # Demo 2: rqt_graph — live node/topic graph (refresh to see connections)
+#   ros2 run rqt_graph rqt_graph &
+#
+#   # Demo 3: rqt_plot — real-time data chart (move turtle to see updates)
+#   ros2 run rqt_plot rqt_plot /turtle1/pose/x /turtle1/pose/y /turtle1/pose/theta &
+#
+#   # Demo 4: Talker/Listener — add more nodes to the graph
+#   ros2 run demo_nodes_cpp talker &
+#   ros2 run demo_nodes_cpp listener &
+
+# AI-searchable metadata for template discovery
