Deleting a direct remote Turso database is not supported. Us

Error message

Deleting a direct remote Turso database is not supported. Use the Turso platform API to delete the remote database.

What it means

Guard inside TursoSqliteDatabaseCreator's delete path (ThrowIfDirectRemoteDelete, called from Delete/DeleteAsync). EF Core's Database.EnsureDeleted/Migrate pipeline calls this creator to drop the database; when the connection is a direct remote Turso database, dropping the whole database cannot be done via the client-side SQLite delete semantics, so the creator refuses instead of issuing an unsupported destructive operation against the remote platform. It fires whenever a delete of a database is requested while the connection string points directly at a remote Turso database.

Solutions

1. Delete the remote database through the Turso platform API (e.g. `turso db destroy`) instead of EnsureDeleted/Delete
2. Point the connection string at a local database if client-side delete is required
3. Recreate/reuse an existing remote database rather than deleting and recreating it
