PR Description
This PR fixes the retry logic in the LangChain Google integration to respect the
retry_delayfield returned by the Gemini API inResourceExhausted(429) errors. Previously, the retry mechanism ignored the server-suggested delay, causing premature retries and quota issues. The fix introduces a custom wait strategy that uses the server-provided delay when available and falls back to exponential backoff otherwise. This aligns client retry behavior with Gemini’s rate limiting guidance, improving reliability and reducing quota exhaustion errors.Relevant issues
