Fix dev migration prompt and embedded db:migrate

doc/DATABASE.md

@@ -19,6 +19,14 @@ That's it. On first start the server:
 
 Data persists across restarts in `~/.paperclip/instances/default/db/`. To reset local dev data, delete that directory.
 
+If you need to apply pending migrations manually, run:
+
+```sh
+pnpm db:migrate
+```
+
+When `DATABASE_URL` is unset, this command targets the current embedded PostgreSQL instance for your active Paperclip config/instance.
+
 This mode is ideal for local development and one-command installs.
 
 Docker note: the Docker quickstart image also uses embedded PostgreSQL by default. Persist `/paperclip` to keep DB state across container restarts (see `doc/DOCKER.md`).
