Introduced a Dockerfile and compose.yml to allow the application to run inside a Docker container. This removes the need for local system-level dependencies and offers a more predictable environment for the app. README.md was updated to include Docker-related instructions and an additional environment variable `DOCKER_DB_FOLDER` was added on top of existing ones for Docker support.
Changes have been made to support environment specific database file handling. By introducing a new environment variable "DB_FILE", the application's runtime now reads the database file path from the environment. In addition, subdirectories will now be automatically created if they don't exist and more detailed error messages will be printed in case of a failure. Environment variable setup and project building instructions were also updated in the README file.
