When we ported the fuzzer's result comparison logic over from JavaScript to the c++ shell helper, we made numeric comparison stricter with exact equality comparisons. This has led to the proliferation of fuzzer BFs that boil down to different versions having slightly different floating point precision values (i.e. when a constant folding optimization reorders constants in $sum when it's not fully associative).

Since we've decided these optimizations are acceptable despite leading to these small differences in floating point precision, we should port over fuzzy result comparison to the c++ shell helper to reduce BF noise from the fuzzer. This PR has a POC that could be reworked for this purpose. We still use woCompare here, so we should modify this to use approximate equality comparison via Knuth's algorithm instead.
