oSnap frontend requires API to simulate proposal execution.
Summary
API simulates requested oSnap proposal execution against Tenderly API.
Details
In order to simulate execution without forking, contract state needs to be overriden as if transactions were already proposed on oSnap and settled on OOv3:
OptimisticGovernor knows of proposalHash pointing to non-zero asserionId in the assertionIds mapping;
OptimisticOracleV3 has the Assertion with the above assertionId marked as settled.
This has a dependency on state override feature in @uma/common Tenderly simulation library, thus it can be merged only after #4688.
