refactor(types): Use ModelProvider type instead of hardcoded union

Replace 'claude' | 'cursor' literal unions with ModelProvider type
from @automaker/types for better extensibility when adding new providers.

- Update ProviderFactory.getProviderNameForModel() return type
- Update RunningFeature.provider type in auto-mode-service
- Update getRunningAgents() return type
