Update data-annotation-init.sql and Alembic migration to support both new and old deployments: SQL Initialization Script (data-annotation-init.sql): - Add file_version column to t_dm_annotation_results table - Add Alembic version table creation and version insertion - New deployments using this script will have latest schema and Alembic version marked Alembic Migration (20250205_0001_add_file_version.py): - Add column_exists() helper function to detect if column already exists - Add compatibility check in upgrade(): skip if column exists (new SQL init) - Add informative print messages for deployment clarity - Enhanced docstrings explaining compatibility strategy Deployment Scenarios: 1. New deployment with latest SQL script: Schema created with file_version, Alembic marked as applied 2. Old deployment upgrade: Alembic detects missing column and adds it This ensures backward compatibility while supporting fresh installs with complete schema.
