Added global hybrid lemma for hybrids parameterized by oracles that gives
an equality, not just an upper bound. Updated the DDH global hybrid example
to use it. Idea based on the Nominal-SSProve paper "Mechanizing Nested Hybrid
Arguments", https://eprint.iacr.org/2025/1122.

Looks good to me. Minor comment on what I think belongs in statements and what I think should be hidden in proofs.
