Greptile Summary

Updates the Newton package dependency from commit 35657fc to 821d4daafa2df446f6300688ba6a8a1d15e19e36 to fix a regression in the Rerun Visualizer.

• Simple dependency version update that changes a single line in setup.py
• Uses full 40-character commit hash instead of shortened 7-character version (both formats are valid)
• Requires coordinated update in Isaac Sim (tracked separately per PR description)

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is a straightforward dependency version update with a single line modified. The syntax is correct, and the change addresses a documented regression in the Rerun Visualizer. No code logic or breaking changes are introduced.
• No files require special attention

Do we need the newton dep here?

[AntoineRichard]

ya I don't think this should be needed anymore if we refactor the visualizer scripts? @matthewtrepte are those changes ready yet?
