Update migration environment and run script: import additional models in env.py, enhance run.sh to create storage directories and initialize SQLite database with alembic migrations.

Refactor Dockerfile and add run script: streamline multi-stage build, set up application structure, and create a new run script for environment initialization and database migration; update migrations/env.py for improved error handling during model import.

Enhance Docker setup: update docker-entrypoint.sh to set PYTHONPATH, modify Dockerfile to create a proper package structure and adjust permissions for storage and migrations directories; update migrations/env.py to include application root in Python path.

Refactor Docker setup: update docker-compose.yml to define app and db services, adjust ports, and configure environment variables; modify Dockerfile to use Python base image, install necessary dependencies, and set up application structure.
