This issue aims to refactor the current Dockerfile to use a multistage
build approach. The motivation for this change is to:

1. Reduce final image size by excluding unnecessary build-time
dependencies (e.g., gcc, libpython3-dev, etc.)
2. Enhance maintainability by clearly separating build and runtime
concerns
```
Size of the current docker image: 3.82GB
Size of the docker image after multi-stage build: 1.06GB

```

Closes #990
