Module credentials 

Credential management module for Claude Code Switcher

This module provides functionality to save and retrieve API keys for different AI providers. Credentials are stored in plain text since they’re typically managed through environment variables.

Version management strategy:

• Current version: v2 (simplified from previous encryption-based approach)
• Future versions should increment the version number when format changes are needed
