## create_reminder
Schedule a reminder on a Unibox thread and durably enqueue its send.
Use when a thread needs a future follow-up nudge; the response carries the job run acknowledgement.
Creating a reminder replaces any pending one on the same thread; do not stack reminders.
Scopes: unibox:reply
Risk: write; confirmation: none; idempotency: supported.
