Greptile Summary

This PR reverts #5294, which added optional NVTX profiling instrumentation to the NewtonWarpRenderer. The revert removes the nvtx import block, the _nvtx_range decorator (both the live and no-op fallback variants), the functools import, and the three @_nvtx_range(...) decorator applications on update_transforms, render, and read_output. The resulting file is identical to the pre-#5294 state and the revert is clean with no residual references.

Confidence Score: 5/5

Safe to merge — clean revert with no residual references or side effects.

The change is a mechanical revert of a single file, removing optional profiling instrumentation. The resulting file has no dangling imports, no leftover decorator calls, and no logic changes. No P0/P1 issues found.

No files require special attention.
