Migrate Create

This generates sequentially numbered database migration files with paired up/down SQL, scanning your existing migrations to pick the next number and choosing templates based on naming conventions. It looks at your migration name to figure out if you're creating a table, adding columns, dropping something, or making an index, then writes both directions with proper IF NOT EXISTS guards for idempotency. The pattern search against past migrations is a nice touch for consistency, and it logs everything to the agentdb memory system under a migrations namespace. If you're hand-rolling migrations instead of using an ORM, this handles the tedious numbering and boilerplate part so you can focus on writing the actual SQL.
