fix: ddx init now creates complete .ddx directory structure

[mehdipiraee]

Summary

Fixes the initialization bug where ddx init only created .ddx.yml but not the .ddx/ directory, causing all subsequent DDx commands to fail with "not initialized" errors.

Problem

After running ddx init, users would see:

• ddx diagnose → "Initialization: ✗ Not initialized"
• ddx update → "❌ Not in a DDx project. Run 'ddx init' first."
• ddx contribute → "❌ Not in a DDx project. Run 'ddx init' first."

This happened because isInitialized() checks for the .ddx/ directory:

func isInitialized() bool {
    _, err := os.Stat(".ddx")
    return err == nil
}

But ddx init only created .ddx.yml, not .ddx/ directory.

Solution

Modified ddx init to create the complete directory structure as documented in README:

your-project/
├── .ddx/
│   ├── prompts/        # AI prompts and instructions
│   ├── templates/      # Project and file templates
│   ├── patterns/       # Reusable code patterns
│   └── configs/        # Tool configurations
└── .ddx.yml           # DDX configuration

Changes

• Added code to create required subdirectories in .ddx/:
  • prompts/ - AI prompts and instructions
  • templates/ - Project and file templates
  • patterns/ - Reusable code patterns
  • configs/ - Tool configurations
• Improved error handling for directory creation
• Added clear comments explaining the purpose

Testing

Before Fix:

ddx init
ddx diagnose  # Showed "Initialization: ✗ Not initialized"

After Fix:

ddx init
ls -la .ddx/  # Shows prompts/ templates/ patterns/ configs/
ddx diagnose  # Shows "Initialization: ✓ Initialized" ✅
ddx update    # No longer shows "not initialized" error ✅

Verification

• ddx init creates complete directory structure
• ddx diagnose shows "Initialization: ✓ Initialized"
• ddx update recognizes project as initialized
• ddx contribute recognizes project as initialized
• Directory structure matches README documentation
• Clean test environment confirms fix works

Files Changed

• cli/cmd/init.go - Added directory structure creation
