Description
As we see CLB is too slow for fuzzing #60 and it does not seem to be fixable.
Due to most of Tx correctness checks should be validated by our off-chain code anyway (blocked by #65), emulator can be implemented by only recording current UTxO state. That is: if we do not count Plutus fees, which would be out of scope of this task.
TODO:
- Implement UTxO store and its querying
- Add support for ADA selection and minada enforcement without
makeTransactionBodyAutoBalance - Support submitting
- Support time
- Parameterize tests around backends

Research direction
No files or test entry points are named. Start by reading the context in #60 and the off-chain correctness work blocked by #65, then map the existing backend abstraction and tests. Done means implementing the UTxO store and queries, ADA selection and min-ADA enforcement, submission and time support, and parameterizing tests across backends.
