New linter with autofixes

[ZedThree]

@Beliavsky has used an LLM to create a bunch of python scripts that can autofix a whole bunch of issues. I imagine quite a lot of them could be incorporated into Fortitude

By the way I thought of having Codex use Rust for speed, perhaps contributing your project. But a typical workflow may be

• compile original and run
• fix source
• compile new source and run
• compare results

and I found that typically the fix source step in Python was faster than a compile, let alone compile and run. So I will continue in Python.
