Handler traits and implementations for MCP operations

This module contains the decomposed handler system with focused modules:

• traits: All handler trait definitions
• composite: Composite handler pattern for multi-type handlers
• wrapper: Handler wrapper infrastructure with metadata
• implementations: Concrete handler implementations
• utils: Utility functions for creating handlers from closures
