Hey @lailoo, thanks for adding opencode-plugin-auto-update to the ecosystem table and for catching the duplicate PR situation.

If you got a chance to try the plugin, I would love to hear what you thought. Even a quick note on what worked well or what felt confusing would help a lot.

If you are open to it, I would also be happy to chat. We can keep it here on GitHub, or use whatever you prefer.
