Replace inline migration logic with proper Alembic migrations: - 001: Initial schema (creates memories table with FTS) - 002: Add multi-user and secrets columns (user_id, is_sensitive, vault_path, encrypted_content) Migrations run automatically on app startup. Existing databases are handled gracefully with IF NOT EXISTS / column existence checks.
