Stateless fuzzing generates complete transactions but previously discarded everything except calldata. This meant values such as
msg.valuewere not preserved consistently across execution, corpus storage, counterexamples, and replay.This PR carries a complete
BasicTxDetailsthrough the stateless fuzzing path. It also keeps existing failure artifacts replayable.This is PR 1 because a shared transaction representation is the foundation for unifying stateless and invariant fuzzing around sequences. Follow-up PRs will unify transaction generation and dictionaries, sequence generation and mutation, and finally the execution campaign. Those architectural changes are intentionally out of scope here.
