User-triggered episode sends and feed updates lived only in memory queues, so a restart dropped them. Store JSON-safe payloads in send_outbox, claim/lease them into the existing balancer, and restore pending rows on process start. Co-authored-by: Kovalenko K. <kintonkk@gmail.com>
Startup reclaim+drain would otherwise pick up a row already claimed onto the memory queue and send it twice. Leave rows pending until RecordBalancer has finished restoring the outbox. Co-authored-by: Kovalenko K. <kintonkk@gmail.com>

What
A process restart used to drop pending episode sends and user-triggered feed updates: they lived only in
queue.QueueinsideRecordBalancer.send_outboxstores a JSON-saferec/updatepayload (pending→leased→done/failed). The in-memory balancer is still used in-process; on start expired/forced leases are reclaimed and pending rows are drained. Telegram upload/send logic is unchanged.Details
