Feature Request: Add OpenCode Agent Support

[Copxer]

Summary

It would be great to add support for an OpenCode agent in Agent-OS.
This would make it easier to integrate OpenCode workflows directly into the system.

Motivation

• OpenCode provides a flexible framework for AI-driven automation.
• Adding it as an agent will help users automate tasks such as documentation, planning, and code generation inside Agent-OS.
• This integration could expand adoption by developers already working with OpenCode.

Proposed Solution

• Define a new opencode within the existing agent registry.
• Provide configuration options in .opencode/agent/ similar to other supported agents.
• Allow mapping OpenCode models (e.g., copilot/gpt-4o-mini, copilot/gpt-4.1) to this new agent.

Additional Context

I’ve been experimenting with Agent-OS and noticed that adding OpenCode would reduce manual setup for common workflows.
Happy to help test or contribute an implementation if this feature is approved.

Thanks for considering this request!
