Detailed Description

Circuit breaker pattern for fault tolerance and resilience.

Implements the Circuit Breaker pattern to prevent cascading failures in distributed systems by temporarily blocking requests to failing services.

State Machine:

• CLOSED: Normal operation, requests pass through
• OPEN: Failure threshold exceeded, requests immediately fail
• HALF_OPEN: Testing recovery, limited requests allowed

This implementation consolidates circuit_breaker from thread_system, monitoring_system, and network_system into a single, reusable component.
