Demo video walkthrough: yard drawing → agent run → setup plan shown

[nakia-lab]

Create a short demo video (~3 min) showcasing the following flow:

1. Draw a yard using the UI (demonstrate basic yard outline and features input)
2. Run the agent to process the yard configuration
3. Show the generated setup plan: zone perimeters, cutting heights, and schedule

The video should illustrate the end-to-end experience of quickly configuring a robotic lawn mower using the agent, emphasizing simplicity and automation.
