- Changed `DATABASE_URL` in `data/README.md` to use a relative path for better compatibility.
- Removed the reference to `BACKUP.md` in `DOCKER.md` as it is no longer relevant.
- Updated `.gitignore` to only exclude `.db` files in the `/data/` directory and preserve backups.
- Modified `docker-compose.yml` to switch database and backup paths to `dev.db`, aligning with the current development setup.
