Add MCP (Model Context Protocol) integration to Wheels CLI

[bpamiri]

Summary

This PR implements comprehensive MCP (Model Context Protocol) support for AI-powered development tools through new CLI commands. MCP enables AI assistants like Claude Code, Cursor, and Continue to better understand and work with Wheels projects.

New CLI Commands

• wheels mcp setup - Installs and configures MCP server with automatic port detection
• wheels mcp status - Shows current MCP installation and configuration status
• wheels mcp test - Validates MCP setup and connection
• wheels mcp update - Updates MCP server to latest version
• wheels mcp remove - Cleanly removes MCP integration

Key Features

• Dynamic port detection from server.json, .env, or running server
• Multi-IDE support for Claude Code, Cursor, Continue, and Windsurf
• Smart template system using app/snippets folder following Wheels conventions
• Automatic npm dependency management with @modelcontextprotocol/sdk
• Comprehensive error handling with helpful user feedback

Technical Details

Files Added

• cli/src/models/MCPService.cfc - Core service for MCP management
• cli/src/commands/wheels/mcp/setup.cfc - Setup command
• cli/src/commands/wheels/mcp/status.cfc - Status command
• cli/src/commands/wheels/mcp/test.cfc - Test command
• cli/src/commands/wheels/mcp/update.cfc - Update command
• cli/src/commands/wheels/mcp/remove.cfc - Remove command
• templates/base/src/app/snippets/mcp-server.js.txt - MCP server template

Architecture Decisions

• MCP server template lives in app/snippets following Wheels generator conventions
• Template distributed with base application template for consistency
• CLI reads from snippets folder like other generators
• Uses {{PORT}} placeholder for dynamic port configuration
• Integrated with WireBox dependency injection

Testing

Tested with Docker test environment on port 60006 at templates/base/src:

• ✅ Setup command successfully installs MCP server
• ✅ Port detection works correctly
• ✅ Dependencies install via npm
• ✅ Status command shows correct configuration
• ✅ Test command validates setup
• ✅ Update command refreshes server file
• ✅ Remove command cleanly uninstalls

Impact

This integration enables AI assistants to:

• Access real-time project structure and configuration
• Generate models, controllers, and migrations using Wheels conventions
• Execute tests and server commands directly
• Understand routes and database schema
• Provide more accurate and context-aware assistance

Breaking Changes

None - this is a new feature that doesn't affect existing functionality.
