Add opencode support

[khalilgharbaoui]

Summary

Add support for opencode in code-insights.

Why

opencode is a relevant workflow/tooling target, and supporting it would make code-insights more useful for developers who use it in their day-to-day setup.

Proposed scope

• Detect and support opencode-related inputs/configuration
• Ensure code-insights can parse and surface useful information for opencode workflows
• Keep the implementation aligned with existing integrations and architecture

Expected outcome

Users should be able to use code-insights with opencode without custom hacks or manual workarounds.

Acceptance criteria

• opencode is recognized as a supported target/integration
• core code-insights functionality works with opencode
• documentation includes basic setup/usage for opencode
• tests cover the new support

Hi @khalilgharbaoui — thanks for the request and for taking the time to write it up so clearly! 🙏

opencode support is a great fit for Code Insights. We already have a multi-source provider architecture (Claude Code, Cursor, Codex CLI, Copilot CLI, Copilot) so adding opencode would follow the same pattern.

We'll take a look at opencode's session/history format and scope out what a provider implementation would look like. Will update this issue when we have a plan.

Thanks again for the suggestion!
