/**
 * migrate-v2 step: tasks
 *
 * Port v1 scheduled_tasks into v2 session inbound DBs.
 *
 * v1: scheduled_tasks table (schedule_type, schedule_value, next_run)
 * v2: messages_in rows with kind='task' in per-session inbound.db
 *
 * Requires: db step must have run first (agent_groups + messaging_groups seeded).
 *
 * Usage: pnpm exec tsx setup/migrate-v2/tasks.ts <v1-path>
