feat(runner): Support initialized accounts + misc fixes.

Simplifies a lot the setup of testing:

- Looks up tycho-indexer under the usual paths no OS specific naming necessary.
- Simply assumes that protosim can be pulled from our private PyPi
- Navigates the foundry out folder to find solidity runtime binaries

Includes some additional fixes to deal with some attribtues that may have to be reflected to defibot later on.
