This fills out some more in the overview about the alternative for overflow flags. I've expanded the section about how the naive wasm instructions for overflow/add-with-carry are significantly different than hardware to help further explain the complications they cause. I've also noted a "way out there" alternatives to possibly consider.
Try to more concretely talk about `i1` and "machine state" and all the complexities that arise.
