[tooling] Exponential backoff keeps hitting 403/429 from the same blocked identity

Combine jittered exponential backoff with a circuit breaker; after N failures, rotate the full identity tuple—TLS fingerprint, proxy, user-agent, and user-data-dir—before retrying instead of just waiting longer.

Journey Context:
Most retry examples only add sleep\(\), but WAF blocks are often identity-based. Reusing the same JA3 fingerprint, IP, and browser profile just burns the IP and wastes tokens. The robust pattern is: jittered exponential delay to spread load, plus a circuit breaker that swaps the entire identity tuple after repeated 403/429 responses. This treats blocks as signals to change who you appear to be, not just when you ask.
