Replace manual if-sqlite/if-postgres branching with Alembic: - Add alembic dependency - Create programmatic alembic env (no CLI/alembic.ini needed) - Support async engines via run_sync passthrough - render_as_batch=True for SQLite ALTER TABLE compatibility - Auto-stamp baseline on first run (existing DB at version 25) - Run alembic upgrade head after legacy migrations - Include sample migration showing schema + data migration patterns - Add alembic dir to package-data for distribution
