I’m not entirely confident that this PR will be merged. Over time, additional changes may introduce merge conflicts, which could further reduce its chances of being accepted.

As a result, I’ve decided to maintain my own fork of opencode. This message is for anyone interested in trying out these features—you can visit my fork and refer to the “Notes” section in the README.md for detailed guidance.

The setup process is straightforward and easy to follow.
