Apply proper TypeScript type corrections without any unsafe casts:
- Fix unknown/never/{} types from decompilation
- Correct function signatures and parameter types
- Add missing type declarations and interfaces
- Fix Ink component prop types
- Update API client/provider type annotations
Test files with mock data casts are included as-is (acceptable pattern).

Add xAI Grok as a new API provider. Reuses OpenAI-compatible message/tool
converters and stream adapter with Grok-specific client and model mapping.
Default model mapping:
opus → grok-4.20-reasoning
sonnet → grok-3-mini-fast
haiku → grok-3-mini-fast
Users can customize mapping via:
- GROK_MODEL env var (override all)
- GROK_MODEL_MAP env var (JSON family map, e.g. {"opus":"grok-4"})
- GROK_DEFAULT_{FAMILY}_MODEL env vars
Activation: CLAUDE_CODE_USE_GROK=1 or modelType: "grok" in settings.json
Also integrates with /provider command for runtime switching.
