Remove internal/content package and use engine directly

- Eliminate content.Enhancer wrapper around engine.ContentEngine
- Update cmd/enhance.go to call engine.ProcessFile/ProcessDirectory directly
- Update sites/manager.go to use engine.NewContentEngineWithAuth directly
- Remove unused EnhancementConfig and discovery configuration logic
- Simplify enhance command to use input path as site ID
- Remove CLI config dependency from config package
