OpenTracing

Provides a standardized API that allows switching between tracing backends like Jaeger or Zipkin without code changes, enabling flexibility in observability strategies as highlighted in the README.

Uses AsyncLocal in IScopeManager for automatic span propagation across async/await operations, simplifying instrumentation in asynchronous code, as demonstrated in the provided examples.

Supports both dependency injection for clean architecture and GlobalTracer fallback for libraries, ensuring compatibility across various application types and frameworks.

Includes convenient methods like Tags.Error.Set() for marking errors on spans, streamlining debugging and monitoring in distributed systems.
