One-off helper to re-import specific FN-* tasks from .fusion/tasks/<id>/task.json
back into the live SQLite DB after a restore. Mirrors the column list used by
db-migrate.ts:migrateTasks but uses INSERT OR IGNORE so existing rows are
never overwritten. Used to rebuild FN-5415..FN-5425 after the FN-5407 backup
corruption recovery.
