refactor: simplify devcontainer configuration and remove workspace mount (#113)

# Simplify DevContainer Configuration

This PR streamlines the DevContainer setup by:

1. Standardizing indentation in the Dockerfile for better readability
2. Removing unnecessary workspace directory setup in the Dockerfile
3. Removing custom mount configuration in devcontainer.json
4. Improving formatting in devcontainer.json for better readability

These changes simplify the DevContainer configuration while maintaining the core functionality of the Nix-based development environment.
