Module env_api_keys 

Environment variable-based API key resolution (LAST RESORT)

Provides environment variable detection as a last-resort fallback for CI/CD, containers, and other automated environments.

For local development, credentials should be stored via oxicode setup in ~/.config/oxicode/auth.json. This file-based approach is more reliable than environment variables, which are lost when the shell restarts.

Auth priority (see provider_registry.rs):

1. Runtime override (–api-key)
2. Stored credential (auth.json)
3. OAuth token
4. Ambient credentials (AWS IAM, Google ADC)
5. Environment variable ← this module
