Description

When a provider returns a non-transient 429 (e.g. GitHub Copilot "exceeded your weekly rate limit"), the session retries forever instead of stopping. User has to press Esc to exit.

The AI SDK marks all 429s as isRetryable: true, so retryable() never returns undefined for these errors.
