"""Add consumer_inbox table for outbox idempotency.

Revision ID: 0065
Revises: 0064
Create Date: 2026-07-29

Without idempotency, a worker crash between sending an email/webhook
and marking the event as published can lead to duplicate deliveries.

This migration creates a consumer_inbox table that tracks which
consumers have already processed which events.
