🚀 Major Enhancement: Claude CLI Support & Strategy Pattern Architecture

This PR introduces comprehensive Claude CLI support with a robust Strategy Pattern architecture, bringing the MCP installer to v0.6.0 with significant performance and extensibility improvements.

✨ New Features

Claude CLI Integration

• Automatic Detection: Detects if claude CLI is available at startup
• Immediate Availability: Servers installed via CLI are available instantly (no restart required)
• Graceful Fallback: Falls back to Claude Desktop config if CLI unavailable
• Enhanced UX: Clear feedback on installation method and availability status

Strategy Pattern Architecture

• Extensible Design: Clean interface ready for multiple installation environments
• Performance Optimized: Early strategy detection (1 call vs 4 calls per operation)
• Future-Ready: Prepared for Docker, Kubernetes, VS Code Extensions, and more
• Maintainable: Eliminated conditional branching duplication throughout codebase

🏗️ Technical Improvements

Architecture Changes

• Added InstallationStrategy interface with concrete implementations:
  • ClaudeCliStrategy - For claude CLI installations
  • ClaudeDesktopStrategy - For traditional config file approach
• Global strategy initialization at server startup
• Unified installation interface across all environments

Performance Enhancements

• Before: 4 hasClaudeCLI() calls per installation operation
• After: 1 hasClaudeCLI() call per server startup
• Eliminated redundant environment detection
• Streamlined installation flow

Code Quality

• Removed legacy installToClaudeCLI/installToClaudeDesktop functions
• Simplified conditional logic throughout the codebase
• Better separation of concerns
• Enhanced error handling and user feedback

📦 Installation & Usage

For Claude CLI (New - Recommended):

claude mcp add mcp-installer npx --args @o2alexanderfedin/mcp-installer

For Claude Desktop (Existing):

{
  "mcpServers": {
    "mcp-installer": {
      "command": "npx",
      "args": ["@o2alexanderfedin/mcp-installer"]
    }
  }
}

🔄 Backward Compatibility

✅ No Breaking Changes: All existing Claude Desktop installations continue to work exactly as before
✅ Enhanced Experience: Existing users get improved performance and better error messages
✅ Seamless Migration: No action required for current users

🧪 Testing

• ✅ TypeScript compilation passes
• ✅ Build system works correctly
• ✅ Module loads without runtime errors
• ✅ Backward compatibility verified
• ✅ Strategy pattern functionality confirmed
