Docs/Example For New Rerun API

[jeff-hykin]

Closes DIM-540

Greptile Overview

Greptile Summary

This PR adds documentation and examples for the new Rerun visualization API. The changes demonstrate how to use RerunBridgeModule with custom blueprints to automatically visualize LCM streams in Rerun.

Key Changes:

• Added rerun_bridge() to the camera demo for easier visualization testing
• Documented how to integrate RerunBridgeModule into custom blueprints
• Created a new grayscale camera example showing the full pipeline from camera → processing → visualization

Issues Found:

• Documentation contains incorrect import path for CameraModule (missing .sensors in path)

Confidence Score: 4/5

• Safe to merge after fixing the import path in documentation
• The code changes are minimal and correct - adding rerun visualization to camera demo and creating a well-structured example. However, the documentation contains an incorrect import path that will cause runtime errors if users copy it directly. This is a simple fix that prevents the PR from receiving a perfect score.
• Pay close attention to docs/usage/visualization.md - fix the import path before merging

Important Files Changed

Filename	Overview
dimos/hardware/sensors/camera/module.py	Added rerun_bridge() import and included it in demo_camera autoconnect, enabling visualization for camera demo
docs/usage/visualization.md	Added documentation section for custom blueprints with RerunBridgeModule, but contains incorrect import path for CameraModule
examples/camera_grayscale.py	New example showing grayscale image processing with camera and rerun visualization

Is this supposed to be python not py?

[jeff-hykin]

Both get highlighting, same with js and JavaScript. But it would be good to be consistent.

[paul-nechifor]

Invalid path.

Between the old Rerun API and the new lies a membrane of translation. The examples compile, but do they understand? Documentation bridges realities—choose your words carefully.
