meta: add initial GOVERNANCE.md

[thoughtpolice]

After lots of discussion, we've finally achieved a draft of the governance document!

This is a draft, as it is fundamentally incomplete; that will require the election of the initial set of 5 Jujutsu Maintainers, after an open self-nomination period! Stay tuned for more on that.

This is the result of a lot of back and forth, the weekly efforts of the governance working group, currently consisting of:

• Martin von Zweigbergk (martinvonz)
• Waleed Khan (arxanas)
• Emily Shaffer (nasamuffin)
• Austin Seipp (thoughtpolice; yours truly)

Many thanks as well to emeritus member Khionu Sybiern, who helped kickstart this whole process.

You forgot to add it to the website and renaming the old temporary governance.

Seems like a solid start, and I'm glad to see other community members chiming in. Should we push this review more in the Discord starting next week, when people are likely to be back from vacationing?

New update looks good to me, for starters. Only thing I might add is - what's the process for modifying governance.md? Do changes need to go to a maintainer vote through the regular process? Since this is a good start but fairly bare-bones, I think it's worth outlining how we intend to update it later if/when we need to.

I think basically we expected to use the Decision-Making process for modifying governance.md.

My comments are very much a result of a first impression. I hope they'll be helpful, but I wasn't part of drafting this document, so I might be retreading discussions that already happened, or I might not be following the spirit of what people were going for at all. If they aren't helpful, I'm happy to be overruled.

This was approved by the community in #5535. I think that means you can go ahead and merge this, @thoughtpolice
