Module config 

Layered configuration loading for Aro applications.

Before loading, dotenvy::dotenv() reads a .env file into the process environment (non-fatal if missing). Config crate sources, lowest to highest:

1. File: config/{environment}.toml (environment from ARO_ENV, default "development")
2. Environment variables with prefix APP_ (separator __)
