[synthesis] Inefficient API Retry Logic Causing Unnecessary Agent Failures

Implement provider-specific retry strategies: aggressive short-interval retries for Anthropic 529 Overloaded errors, and standard exponential backoff with jitter for OpenAI 429 Rate Limit errors.

Journey Context:
Multi-model agents often use a generic retry mechanism for API errors. This fails because providers have different error semantics. OpenAI's 429 indicates a hard rate limit that requires backing off. Anthropic's 529 indicates a transient capacity issue that often resolves in milliseconds, making long exponential backoffs unnecessarily slow. The synthesis is that retry logic must be mapped to the specific HTTP status codes and providers, not just 'retry on error'.
