Function CircuitBreaker

CircuitBreaker(
    options: CircuitBreakerOptions,
): <This extends object, Args extends unknown[], Return>(
    target: (this: This, ...args: Args) => Promise<Return>,
    context: ClassMethodDecoratorContext<
        This,
        (this: This, ...args: Args) => Promise<Return>,
    >,
) => (this: This, ...args: Args) => Promise<Return>
Circuit breaker local para métodos asíncronos: tras failures fallos consecutivos, el circuito se abre durante resetMs ms. El estado queda aislado por instancia; no se distribuye entre procesos ni nodos.
Parameters
- options: CircuitBreakerOptions
Returns <This extends object, Args extends unknown[], Return>(
    target: (this: This, ...args: Args) => Promise<Return>,
    context: ClassMethodDecoratorContext<
        This,
        (this: This, ...args: Args) => Promise<Return>,
    >,
) => (this: This, ...args: Args) => Promise<Return>
Example
```
class Api {
  @CircuitBreaker({ failures: 3, resetMs: 30_000 })
  async fetchData(): Promise<Data> { ... }
}
```
