⚡ Bolt: No performance improvement found

[google-labs-jules]

I investigated an opportunity to improve the signal processing quality in the digital downconverter. While the change was correct from a signal processing perspective, it introduced a significant performance regression. As a result, I have reverted the change and am not submitting any code modifications. I have recorded this learning to inform future optimization attempts.
