feat: add dynamic model discovery and routing for OpenCode provider

- Update isOpencodeModel() to detect dynamic models with provider/model format
  (e.g., github-copilot/gpt-4o, google/gemini-2.5-pro, zai-coding-plan/glm-4.7)
- Update resolveModelString() to recognize and pass through OpenCode models
- Update enhance route to route OpenCode models to OpenCode provider
- Fix OpenCode CLI command format: use --format json (not stream-json)
- Remove unsupported -q and - flags from CLI arguments
- Update normalizeEvent() to handle actual OpenCode JSON event format
- Add dynamic model configuration UI with provider grouping
- Cache providers and models in app store for snappier navigation
- Show authenticated providers in OpenCode CLI status card
