     * The full ClankerSaddle schema in one migration (plan 11: every
     * earlier migration flattened — the database is not deployed, so
     * tear-down-and-recreate replaced incremental evolution). Covers:
     * projects and their links; the plan-12 goals (with links —
     * plan 15 C1 deleted `goal_blocks` and C2 deleted `goal_comments`:
     * the goal agent's blocks and comments ride the run task's own
     * rows) and the
     * flattened task shape (`goal_id`, `kind`, `mode`,
     * `creator`, `enqueue_after_task_id` — the subtask machinery's
     * parent_task_id/plan/auto-* columns and the task_dependencies
     * table are gone); tasks with comments, typed blocks, progress
     * and the draft-lifecycle columns (`status` defaults to
     * 'draft'); saddle registrations with git identity
     * and the per-saddle token; the session + command + raw-log audit
     * trail; the plan-13 daemon-global entry dedup
     * (`saddle_entry_dedup`); rules and their attachments; project
     * notes; capability tags; and the plan-11 notification tables for
     * task E
     * (`push_subscriptions`, `task_notify_prefs` — included now so
     * D+E needs no migration).
