…nts) Left/right identity of function composition. Both are definitional (closed by conversion); their main value is the simplify-hint registration, which lets /= collapse identity compositions that arise when massaging dmap/expectation goals (e.g. E d idfun).

Two lemmas for identity laws of function composition, also they are added to hint
simplify. I think they're good to be inCore.ec. I'm not sure whether they're good to be in the hint.I found
comp_idfunLwhen cleaning up the proof for Markov inequality.These two lemmas are very small and I'm becoming shamefully lazy, so I just asked Claude Code to migrate it. Forgive me about that.
