🔧 Automatic file:// protocol handling and devcontainer improvements

[httpdss]

🎯 Overview

This PR introduces automatic file protocol handling and improves the development container configuration for better developer experience.

✨ What's Changed

🔧 File Protocol Enhancement

• Automatic file:// prepending - YAML files without protocol automatically get file:// prefix
• Simplified usage - Users can now specify YAML files directly without remembering protocol syntax
• Backward compatibility - Existing file:// prefixed paths continue to work unchanged

🐳 DevContainer Improvements

• Streamlined Python setup - Commented out redundant Python feature (base image already includes Python)
• OpenAI API integration - Added environment variable for AI-powered features
• Better development experience - Optimized container configuration for faster startup

📖 Usage Examples

Before (Manual Protocol)

# Users had to remember the file:// protocol
struct generate file://my-config.yaml ./output

After (Automatic Protocol)

# Protocol is automatically added for .yaml files
struct generate my-config.yaml ./output

# Still works with explicit protocol
struct generate file://my-config.yaml ./output

🔧 Technical Implementation

File Protocol Logic

• Checks if file ends with .yaml and doesn't start with file://
• Automatically prepends file:// protocol when conditions are met
• Maintains existing behavior for all other cases

DevContainer Optimizations

• Removed redundant Python feature installation
• Added OpenAI API key environment variable for AI integrations
• Preserved all existing extensions and settings

✅ Benefits

For End Users

• Simplified commands - No need to remember file protocol syntax
• Reduced errors - Automatic protocol handling prevents common mistakes
• Consistent experience - Works the same way regardless of protocol specification

For Developers

• Faster container startup - Removed redundant Python installation
• AI integration ready - OpenAI API key environment configured
• Better DX - Streamlined development environment

🧪 Testing

• ✅ Verified automatic protocol prepending works correctly
• ✅ Confirmed backward compatibility with explicit protocols
• ✅ Tested devcontainer builds successfully with new configuration
• ✅ Validated all existing functionality remains intact

📁 Files Modified

• struct_module/commands/generate.py - Added automatic file protocol handling
• .devcontainer/devcontainer.json - Optimized container configuration

🔗 Compatibility

• ✅ Backward Compatible - All existing commands continue to work
• ✅ Protocol Agnostic - Supports both explicit and automatic protocol handling
• ✅ Environment Ready - Enhanced development container setup

---

This enhancement improves user experience by removing the need to manually specify file protocols while maintaining full backward compatibility and improving the development environment.
