feat: optimize MCP tools response format with automatic schema generation

- Remove all manual ReturnSchema() methods from tools
- Implement automatic schema generation using reflection
- Unify response format to flat structure with action/success/message fields
- Simplify tool implementation by removing MCPResponse embedding
- Update documentation to reflect new architecture
- Achieve ~70% code reduction while maintaining type safety
