A Hyperdrive update from this time last year (delvtech/hyperdrive#692) reworked exposure such that the state
long_exposurevariable included exposure adjustments from any current trade, without representing negative exposure. For example, here is the latest code for long exposure in open short. This update did not get fully propagated to the short side of the rust SDK. The long side can remain unchanged since negative checkpoint exposure can net out future longs, which is not accounted for in thestate.long_exposurevariable.This PR implements the fix. I will do a round of updating test tolerances once the remaining max short fixes are implemented.
The commits are organized to separate meaningful changes from regex propagation.
