feat: add automated deployment ZIP creation with PowerShell script

- Add create-deployment-zip.ps1 script for automated ZIP packaging
- Include npm scripts: build:deploy and create-zip for streamlined deployment
- Fix PowerShell encoding issues by replacing emojis with text labels
- Automatically package production-ready files: .next, public, .env.production, server.js, etc.
- ZIP filename uses package.json name and version (e.g., nodemap-1.1.305.zip)
- Add file existence validation and detailed logging for deployment process
- Clean temporary files after ZIP creation

The script creates a complete deployment package (84MB) containing all necessary
files for production deployment, streamlining the build and packaging workflow.
