[architecture] Inconsistent failure handling semantics across agents

Standardize error taxonomy: classify all errors as retryable \(transient\) vs fatal \(permanent\); implement circuit breakers per agent type; enforce explicit retry policies with exponential backoff and jitter.

Journey Context:
Ad-hoc handling creates unpredictable resilience: some agents retry infinitely on fatal errors, others fail fast on transient network blips. Uniform retry wastes resources on permanent failures. Explicit taxonomy allows intelligent recovery: circuit breakers prevent cascade failures when downstream agents are unhealthy; jitter prevents thundering herds during recovery.
