I took only a cursory look at the code to make sure that the input vars check would work for EPS. I won't be able to try it until I do the next update of SDEverywhere in the EPS builder in a couple of weeks. Based on the tests and the opt-in decision, I think this can go forward. Another nice and simple optimization with significant impact!

Fixes #896
See issue for details. I left this as an opt-in optimization (enabled via non-public environment variable) since it can have a small effect on model outputs values, but I will probably eventually enable it for En-ROADS since it provides a decent performance improvement.
AI disclosure: I guided Claude Code (Opus 5) to plan and implement the changes, and then I reviewed and refined the changes.
