docs: add ai policy

<!-- Adapted from ghostty's AI_POLICY.md -->

<!--

Notable changes:

- there's no denounce list

- maintainers still must include AI usage

- AI is not strictly welcome, we just must specify the rules for usage

-->

# AI Usage Policy

The Canvas project has strict rules for AI usage:

- **All AI usage in any form must be disclosed.** You must state

  the tool you used (e.g. Claude Code, Cursor, Amp) along with

  the extent that the work was AI-assisted.

- **The human-in-the-loop must fully understand all code.** If you

  can't explain what your changes do and how they interact with the

  greater system without the aid of AI tools, do not contribute

  to this project.

- **Issues and discussions can use AI assistance but must have a full

  human-in-the-loop.** This means that any content generated with AI

  must have been reviewed _and edited_ by a human before submission.

  AI is very good at being overly verbose and including noise that

  distracts from the main point. Humans must do their research and

  trim this down.

- **No AI-generated media is allowed (art, images, videos, audio, etc.).**

  Text and code are the only acceptable AI-generated content, per the

  other rules in this policy.

## There are Humans Here

Please remember that Canvas is maintained by humans.

Every discussion, issue, and pull request is read and reviewed by

humans. It is a boundary point at which people interact with each

other and the work done. It is rude and disrespectful to approach

this boundary with low-effort, unqualified work, since it puts

the burden of validation on the maintainer.

In a perfect world, AI would produce high-quality, accurate work

every time. But today, that reality depends on the driver of the AI.

And today, most drivers of AI are just not good enough. So, until either

the people get better, the AI gets better, or both, we have to have

strict rules to protect maintainers.

Information on how to setup a development environment & project structure can be found [on the wiki][wiki] or in the `/doc/contributing` folder

If you are planning on utilizing an AI model/agent in your contributions, review [our AI policy](./AI_POLICY.md).

## sc07.dev

At time of writing [sc07.dev](https://sc07.dev) has registration approvals enabled. After creating an account an admin will have to approve the account. To accelerate the process, send a message in the mailing list/Matrix/Discord to grab grant's attention.

The project is setup as a monorepo, with the frontend, backend and admin interface all in one place.

If you are planning on utilizing an AI model/agent in your contributions, review our AI policy (located in the project root at `/AI_POLICY.md`).
