Module enhanced_registry 

An advanced handler registry with metrics and enhanced features. Advanced registry with MCP protocol handler support and observability.

This registry extends the crate::registry::Registry base with:

• MCP protocol handlers (elicitation, completion, resource templates, ping)
• Handler call statistics (invocation count, duration, errors)
• Capability tracking per handler
• Thread-safe concurrent access via DashMap

When to Use This Registry

Use EnhancedRegistry when you need:

• MCP protocol handler registration (elicitation, completion, etc.)
• Observability into handler usage patterns
• Production-grade monitoring and debugging
• Capability discovery per registered handler
