Lightweight demo focusing on sensor data and configurations

[bburda]

Summary

Create a lightweight demo that runs without Gazebo, showcasing ros2_medkit's data monitoring, configuration management, and fault detection on simulated sensor nodes.

---

Proposed solution

Why This Demo

• Runs anywhere - No Gazebo, no GPU, works in CI and Codespaces
• Fast startup - Seconds vs minutes
• Focus on diagnostics - Pure ros2_medkit features without robot complexity
• Good for tutorials - Simple environment for learning

Demo Setup

Simulated sensor nodes publishing realistic data with configurable fault injection, for example:

Sensor Demo (no Gazebo)

Additional context

Benefits:

• CI-friendly - Fast, reliable, no GPU
• Tutorial base - Simple environment for docs/workshops
• Isolated testing - Test ros2_medkit without robot complexity
• IoT applicable - Same patterns work for non-robot sensors
