Module observability 

Observability module for comprehensive monitoring, tracing, and metrics collection.

This module provides:

• OpenTelemetry integration with distributed tracing
• Prometheus metrics export
• Structured logging with correlation IDs
• Performance monitoring with minimal overhead (<2%)
• Health monitoring and check endpoints
• Performance profiling with flame graphs and regression detection
