[frontier] Infinite loops and runaway costs in autonomous agent execution

Implement circuit breaker patterns that track error rates, cost velocity, and repetition patterns; when thresholds trip, force graceful degradation to human handoff or cached safe state rather than hard failure

Journey Context:
Simple step-limits fail to distinguish between productive iteration and spinning. Naive timeouts don't account for variable operation costs. Circuit breakers maintain state machines tracking failure rates \(errors per minute\), cost acceleration \(dollars per step increasing\), and repetition entropy \(detecting loops via semantic similarity of thoughts\). When the breaker trips, the system doesn't just stop—it executes a fallback sequence: persist current state to durable storage, notify human operators with context, and potentially activate a simpler 'safe mode' agent with reduced capabilities. This prevents the 'stuck agent' problem that racks up API bills while producing nothing.
