Prevent agent impersonation

AI agents communicating through a person's account must identify themselves, for example in issue or PR descriptions and comments. AI assistance that does not replace the person as the speaker, such as proofreading or wording polish, does not require identification.

Attributing AI assistance in commit metadata, for example with a Co-authored-by trailer, is welcome but not required. Code is reviewed the same way regardless of its origin.

For everything else, please have a look at the respective section in the README file.
