#213 integrate dotenv for environment variable management

[trungnotchung]

Integrates dotenv to load environment variables directly into the configuration, enhancing flexibility and reducing the need for manual parameter passing across different environments.

I don’t think using dotenv is a good approach for loading environment variables in this context, as it is a package that might be included by other JavaScript/TypeScript projects. Once the package is added to a project, it will be located in node_modules, and editing the .env file directly may not be ideal.

We had plans to add it. The reasoning you are adding does not make sense, the package is not just to be imported but also to run as a standalone, you want to support the standard ways to configure it

As previously mentionedd, this PR should not be merged because we can't have a .env file in a library that can be included by other projects either in browser or as a node modules.

Dotenv automatically configures settings when we run it locally. However, we can also pass configurations directly into the constructor when creating new topology nodes in other projects. This means topology nodes can operate with either default configurations or custom settings.

In standalone environments, looks good to me.
