OpenCode support

I love what you have built. Thanks for sharing.

It would be amazing if this had support for OpenCode.

It's on the ACP list : https://agentclientprotocol.com/overview/agents.

Thanks

Came to make the same request and see Mark already did. Looks very promising!

I had a go but can't seem to get auth to inherit into the spawned opencode. Please take a look at the branch if you wanna try and get it working: #10
