Add matplotlib to the benchmark extra's docstring/README package list

[evanjain-dot]

pyproject.toml's benchmark extra gained matplotlib in #235 (figures.py
needs it to render strategy-comparison PNGs), but cli.py's module
docstring and README's install snippet still listed the old three
packages. Closes #244.

@yakew7 - new PR touching a path you own, please review.

[yakew7]

@ahmdkaml @Shreyash0712 if u want you can review it asw

[Shreyash0712]

Good to go. It's just adding matplotlib.

[Shreyash0712]

@yakew7 btw what perms do I have? can I merge stuff asw? Idts as I don't see the button to do so.

[yakew7]

@Shreyash0712 you've got write access now (can push, open PRs, comment, review, etc.) and you're a co-code-owner of /explainers/ in CODEOWNERS - so on an explainers-only PR your approval satisfies the required-review gate and you'll see the merge button.

main is protected though: every PR needs 1 approving review, and it has to come from whoever CODEOWNERS says owns the touched paths (require_code_owner_reviews). this PR touches faircode/cli.py, which only I'm listed as owner for, so your approval alone doesn't unblock it - that's why the button isn't showing for you here, not a gap in your account.

on higher perms later - not ruling it out, not doing it yet either. you're the most prolific explainer contributor by far and the catch on #277 was a genuinely good piece of review, so it's earned you real trust. I'd want to see that extend past explainers first - reviewing/contributing to tests, scripts, or docs over the next couple months - before I'd extend CODEOWNERS further or anything closer to admin. will revisit then.

[Shreyash0712]

I see. Love the system. A lot has changed in the repo since I joined. I'll do my best.

[yakew7]

yeah the repo grew a lot more with some active contributors asw

[Shreyash0712]

Okay so can you make it so the bot starts to tag me in PRs as well? That way I'd get a notification.

[Shreyash0712]

Not just from my domain - all of them. I don't mind. I'll review whenever I get time. @yakew7
