Coercion lemmas for ℝ → EReal #
Several IEEE32Exec interval soundness proofs move between real bounds (proved in ℝ) and
overflow-safe endpoint reasoning (done in EReal).
This file centralizes small “coe distributes over min/max” rewrite lemmas for the interval soundness modules.
We do not mark these as simp lemmas: they are intended for targeted rewriting in interval
proofs, and we want to avoid surprising simp behavior in unrelated developments.
