v3.6.1

Fixed

• Fixed queue:work --stop-when-empty exiting when jobs remain pending behind a queue rate limit.
• Workers now wait for the nearest rate-limit window and retry when a rate-limited queue is not empty.
• Preserved normal --stop-when-empty behavior for genuinely empty queues and existing multi-queue processing order.

Tests

• Added regression coverage for rate-limited pending queues, empty queues, and multi-queue rate-limit behavior.
