Add circuit-breaker mode for unstable upstream model provider

[Flamki]

Problem

Repeated provider failures can cascade into poor UX and excessive latency.

Scope

• Add failure threshold + cool-down window
• Short-circuit to fallback behavior while breaker is open
• Emit breaker state changes in status/logs

Acceptance Criteria

• Repeated failures open the breaker
• Breaker half-open/close behavior is deterministic
• Dashboard/API status reflects degraded mode

Hi, I'm a backend developer, and I can fix this by implementing a deterministic circuit breaker with configurable failure thresholds, a cool-down window, and transparent state logging.
