[Feature request]: Site Editor live visualization

Before proceeding, is there an existing issue or discussion for this?

• I have done a search for similar issues and discussions.

Description

The Site Editor offers a more modern user interface and superior cross-platform packaging and distribution capabilities compared to alternative visualization platforms.

Implementation Considerations

• Visualize real-time robot positions derived from odometry data.
• Display planned paths and cross-agent traffic dependencies.
• Visualize safe operating zone boundaries (bubbles).
• Stretch goal: Incorporate additional relevant Nav2 status information.

Alternatives

1. ROS2-Enabled Site Editor Application: One approach is to develop a custom application built on the Site Editor that links with ros2_rust. However, this introduces significant challenges regarding the packaging and distribution of a ROS2 application for end-user debugging.
2. WebSocket or REST-Based Bridge to Core RMF Topics: Similar to rmf_web, this approach involves directing the Site Editor to a specified server URI, enabling the real-time streaming of robot positions over the network.

No files or entry points are named. Start by comparing the ROS2-enabled Site Editor approach with the WebSocket or REST bridge, then define how robot positions, planned paths, traffic dependencies, safe operating zones, and optional Nav2 status will reach the visualization. Done means a selected integration approach and a working live visualization for the listed data.
