Hi everyone, I have opened two Pull Requests that propose extensions to the Ractor API. Both have been open for some time, and I would appreciate your feedback on whether they can be approved or if they need changes: 1. Ractor#empty?

Ractor.receive_all Pull Request: https://github.com/ruby/ruby/pull/16105/ Tracker: https://bugs.ruby-lang.org/issues/21869 These are my very first Pull Requests to the Ruby core repository. If I missed any contribution guidelines, or if I need to provide more context or use cases, please let me know.
