Description

Add debugging docs for vllm-spyre.

[github-actions]

👋 Hi! Thank you for contributing to vLLM support on Spyre.
Just a reminder: Make sure that your code passes all the linting checks, otherwise your PR won't be able to be merged. To do so, first install the linting requirements, then run format.sh and commit the changes. This can be done with uv directly:

uv sync --frozen --group lint --active --inexact

Or this can be done with pip:

uv pip compile --group lint > requirements-lint.txt
pip install -r requirements-lint.txt
bash format.sh

Now you are good to go 🚀

thoughts on having the filter be a param here with this as a default? Not really necessary for a first pass but maybe eventually we can point to some docs on the different available tests and what they do

[prashantgupta24]

Yep, good suggestion for the next pass.

I think the section would benefit from using more headers to separate the kinds of debugging you can do but I think this a good start until it grows! LGTM aside from fixing the "Topology ..." header above
