…line check Replace the crude LastRateLimitDigits heuristic with proper X-Ratelimit-Remaining integer tracking and two-tier progressive delays (200ms/500ms). The proactive wait is now context-cancellation-aware. Additionally, waitForCooldown now fails fast when the cooldown duration would exceed the context deadline.
