posthog-v7.57.0

Minor changes

• f69e670 After a failed prompt refetch, the SDK now serves the stale cached prompt for a cooldown period (60 seconds by default) instead of retrying the network on every prompts.get() call. When the failure is a 429, the cooldown follows the Retry-After the server sends, capped at one hour. This keeps a rate-limited client from holding itself against the limit. Matches the behavior the JavaScript SDK already has. — Thanks @jurajmajerik!
