23. Circuit Breaker Logic

Track failures to open the circuit.

Class `Breaker` with `recordFailure()` and `isOpen()` (true if failures >= threshold).

Required in your answer: this.failures++>= this.threshold

Runs in a sandboxed worker

class Breaker {
  failures = 0;
  constructor(threshold) { this.threshold = threshold; }
  // TODO
}
