fix: add module field and ES module support for Smithery CLI compatibility

🔧 Package.json Updates:
- Add 'module' field pointing to './src/index.ts' (required by Smithery CLI)
- Add 'type': 'module' for ES module support
- Add 'exports' field for better module resolution
- Add 'build:smithery' script for Smithery-specific builds

�� TypeScript Configuration:
- Add tsconfig.smithery.json for ES module builds
- Configure separate build output for Smithery (build-smithery/)
- Maintain CommonJS compatibility for existing CLI usage

🚀 Smithery Configuration:
- Update smithery.yaml with custom build command and entry point
- Specify buildCommand: 'npm run build:smithery'
- Set entryPoint: './build-smithery/index.js'

📁 Build Management:
- Update .gitignore to exclude build-smithery directory
- Update clean script to remove both build directories

This resolves the Smithery CLI build error:
'No entry point found in package.json. Please define the module field'

The package now supports both traditional npm installation and
Smithery.ai hosted deployment with proper ES module handling.
