Summary

Reintroduce Claude-class models to OpenCode through OpenRouter instead of restoring the old direct Anthropic auth path.

Why

The repo used to be Claude-first, but the old setup depended on direct Anthropic wiring that we do not want to bring back. OpenCode now supports OpenAI-compatible custom providers, so this should be expressed as a new OpenRouter provider migration rather than a revert.

Scope

Add an explicit OpenRouter provider in dot-config/opencode/opencode.json
Point it at https://openrouter.ai/api/v1 using @ai-sdk/openai-compatible
Add the Claude model IDs we actually want to use
Keep any remaining OpenAI/Codex-specific auth only where still needed
Do not restore opencode-claude-auth

Acceptance criteria

opencode.json has a dedicated OpenRouter provider block
Claude models are selectable through that provider
OpenAI-only provider options are not blindly copied onto the OpenRouter provider
The config documents or encodes the intended default Claude model(s)
