fix: correct Windows package installation script generation

- Fixed package identifier usage: now uses `name` field (winget ID) instead of `id` field throughout Windows script
- Enhanced error handling with exit code checking and consistent [OK]/[ERROR] prefixes for better visibility
- Standardized PowerShell string quotes to single quotes for consistency
