this whole file is a test util, and I don't insist on it existing in this form

if there's a util that does this better -- i'd really prefer to use it, maybe you can point it out

This PR introduces the Scalus node emulator as one of the
Providerimplementations, allowing to write the code against the in-memory Emulator as if it was a real node.It also migrates some of the tests to the scalus emulator, making it drastically faster (180s vs ±3s)
Note on vendored scalus
This PR depends on Scalus features not yet published to npm (
Emulator.withState,getDelegation,getDatum,hasTx). Thevendor/scalus/directory contains a local build of scalus 0.15.0 so reviewers canpnpm install && pnpm testwithout any local setup. The pnpm override in root package.json points to ./vendor/scalus. This will be removed once scalus publishes the new version.
