## Summary by CodeRabbit
* **Chores**
* Improved database initialization for self-hosted deployments with
automatic creation and repair of embedding tables and indexes, applied
only when related base tables and extensions are present.
* Updated pre-deploy process to run Prisma migrations, perform
embedding-table maintenance, and execute additional data migrations as
part of setup.
