✨(gentest): make gentest great

[danceratopz]

The gentest CLI is a really nice tool that can generate and write a Python (pytest) test module to disk given a type 0 transaction hash on a live network. This generates a state_test from the mainnet transaction 0xa41f...06be:

uv run gentest 0xa41f343be7a150b740e5c939fa4d89f3a2850dbe21715df96b612fc20d1906be tests/paris/test_0xa41f.py

Currently, due to its limited transaction type support (type 0 only), it's of limited use. This meta ticket is to track progress of making gentest an easy-to-use CLI tool that can generate test cases for specific issues observed on devnets, and potentially, to allow benchmarking of an EVM's transaction processing using blockchain_tests created from real mainnet data.

While working on the issues below, we should consider and try to ensure that gentest also works on Verkle and EOF testnets.

@raxhvl said he's happy to pick this up! ☺️

Thanks @raxhvl! Above I tried to outline the most obvious tasks for gentest. Please see these as suggestions - if you have any other ideas or inputs, just go for it! I'm also happy to jump in and help out if need be.

Thanks @danceratopz I will comment on individual issues as I start working on them.
