fix(readme): Update readme with consolidated email system improvements and modular directory structure

Clarify that the platform now organizes email functionality into distinct directories (mail/core, mail/delivery, mail/routing, mail/security, mail/services) and update the diagram and key features list accordingly. Adjust code examples to reflect explicit module imports and the use of SzPlatformService.

 #### Key Features
 
 The email handling system provides:
+- **Modular Directory Structure**: Clean organization with clear separation of concerns:
+  - **mail/core**: Core email models and basic functionality (Email, BounceManager, etc.)
+  - **mail/delivery**: Email delivery mechanisms (MTA, SMTP server, rate limiting)
+  - **mail/routing**: DNS and domain routing capabilities
+  - **mail/security**: Authentication and security features (DKIM, SPF, DMARC)
+  - **mail/services**: High-level services and API interfaces
 - **Pattern-based Routing**: Route emails based on glob patterns like `*@domain.com` or `*@*.domain.com`
 - **Multi-Modal Processing**: Handle different email domains with different processing modes:
   - **Forward Mode**: SMTP forwarding to other servers
