feat: add devcontainer configuration and installation script

Add a devcontainer configuration to streamline the development 
environment setup. Introduce an `install.sh` script to install 
the project in editable mode. Update the Dockerfile to use 
the `python:3.13-slim-bullseye` base image and install 
dependencies using `apt-get` for better compatibility.
