     * 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; plan 17
     * flattened again over the force-wake era). Covers: projects and
     * their links; the plan-12 goals (with links — plan 15 C1/C2
     * deleted the goal-side block/comment tables: 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`, plus the force-wake flags folded in
     * from the deleted M0002); tasks with comments and typed blocks;
     * saddle registrations with git identity and the per-saddle
     * token; sessions; the plan-17 UNIFIED EVENT LEDGER (`events`)
     * that replaced `session_commands`, `task_progress`,
     * `session_raw_log` and `saddle_entry_dedup` — every timeline,
     * narrative, resume-notice and log-view surface derives from it,
     * and daemon chunk pushes are idempotent on its
     * UNIQUE(session_id, seq); rules and their attachments; project
     * notes; capability tags; the plan-11 notification tables.
