GitHub limits pull requests to manage noise

GitHub is introducing pull request limits to help manage the increasing volume of contributions to open-source projects. The feature restricts the number of open pull requests a user without write access can submit, aiming to reduce low-quality noise and improve the visibility of valuable contributions. Pull requests generated by AI agents like Copilot will count towards these limits. This initiative addresses a common pain point for maintainers struggling to keep up with the influx of submissions, ensuring that important code changes receive adequate attention.
