## Why
Community expertise is most useful when shared through detailed issue reports, reproduction steps, logs, analysis, and design discussion. Reviewing external code changes requires broader architectural and roadmap context and can divert maintainers from higher-priority work.
## What changed
- State that external code contributions and pull requests are not accepted.
- Replace invited-contributor workflow and CLA guidance with instructions for reporting bugs and requesting features through the issue tracker.
- Remove the pull request template and align the ChatGPT crate guidance with the repository-wide policy.
- Direct vulnerability reports to the security policy.

In order to to this, I created a new `chatgpt` crate where we can put
any code that interacts directly with ChatGPT as opposed to the OpenAI
API. I added a disclaimer to the README for it that it should primarily
be modified by OpenAI employees.
