Module credentials 

Phase 39: Credential Management

Stores and retrieves API tokens for the package registry.

Credentials are stored in a TOML file at ~/.config/logos/credentials.toml with restrictive permissions (0600 on Unix) to protect sensitive tokens.

Token Resolution Order

When retrieving a token via get_token, the following order is used:

1. LOGOS_TOKEN environment variable (highest priority)
2. Credentials file entry for the registry URL

Security

• Tokens are stored in plaintext (like cargo, npm, etc.)
• File permissions are set to owner-only on Unix systems
• The LOGOS_CREDENTIALS_PATH env var can override the default location

Enums
