chore: Add list of things that will not be accepted in CONTRIBUTING.md #1197
Description
We should probably have a list of things that won't be accepted for review in CONTRIBUTING.md.
This will include:
- PRs that cause API providers to diverge from their original API for the purposes of being able to fit other providers
- PRs that have any sort of markdown file which appear to have been added by a coding agent in a PR. PRs that contain these kinds of markdown files will not be immediately rejected, but users will be asked to remove them. If the markdown files are not removed, then the PR will simply stall until the user removes them.
This will be primarily reviewed on a case-by-case basis, because it's not immediately clear how/why a PR may be rejected. Generally though, feature additions that do not provide immediate value to the rest of the library will be rejected as Rig is reaching a point where we can consider it mostly stable (...except the providers).
