v4.0.0.rc2

What's Changed

• Improve default message round-trip consistency by auto-discovering Jackson modules by @JiHongKim98 in #289
• Add worker heart beat by @sonus21 in #290
• Pluggable message ID generation — added RqueueMessageIdGenerator with a
  default UUIDv4 implementation so applications can override message ID generation
  with a custom bean, including time-ordered strategies such as UUIDv7.
• Worker registry for dashboard visibility — added an optional
  rqueue.worker.registry.enabled registry that tracks worker metadata and
  queue-level poller activity for dashboard use.
• Workers dashboard page — added a dedicated workers view showing worker
  identity, queue pollers, last poll activity, and recent capacity exhaustion.
• Queue and workers pagination — added server-side pagination for dashboard
  queue and worker listings, with configurable page sizes.
• Dashboard enqueue controls for scheduled messages — messages in scheduled
  queues can now be moved back to the main queue from the dashboard, including
  explicit front/rear enqueue options for non-periodic messages.
• Dashboard refresh and usability improvements — refreshed queue, worker, and
  explorer UI with improved layouts, duration formatting, feedback modals, and
  more readable queue metadata.
