Add robust environment sharing for install script

- Create .env.install file to store configuration choices
- Modify main-installer.sh to load environment variables
- Use direct sourcing to ensure environment variables are properly passed
- Add explicit logging of environment variable values
- Implement safer method of handling environment across script execution
