Proposal for an IA policy

Very inspired by
https://github.com/ghostty-org/ghostty/blob/main/AI_POLICY.md which I
found quite resonating with my opinions of the topic, after dealing with
recent AI generated PRs.

Thoughts?

Next steps:
- fine tuning / rewording
- linking from CONTRIBUTING.md
- while we are at it, maybe shortening that CONTRIBUTING.md page which
is very wordy and covering stuff that are included in issues/PR
templates.

+# AI Usage Policy
+
+The YOURLS project and organization have strict rules regarding AI usage.
+
+- **All AI usage in any form must be disclosed.** You must state
+  the tool you used (e.g. Claude Code) 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
+  without AI what your changes do and how they interact with code, please do not
+  contribute to this project.
+
+- **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.
+
+- **Pull Requests must be focused.** If you want to submit a PR that fixes a
+  problem, enhances or introduce a new feature, make sure your code does just
+  that. PR containing also white space changes, rewording comments, or
+  tackling several matters will be rejected.
+
+## There are Humans Here
+
+Please remember that YOURLS 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.
+
+**This AI Policy is not an anti AI stance.** It's our way to preserve our
+limited time and resources devoted to this community project.
