fix: resolve GitHub Actions workflow issues

🐛 **Fixes Applied:**

### Package Manager Alignment
- Switched from npm to pnpm throughout workflow to match project setup
- Added proper pnpm cache configuration for faster builds
- Used pnpm/action-setup@v4 for pnpm installation
- Kept npm for version bumping only (pnpm lacks version command)

### Deprecated Action Replacement
- Replaced deprecated actions/create-release@v1 with gh CLI
- Updated to use gh release create for better reliability
- Improved release notes formatting with proper escaping

### Missing Output Declaration
- Added proper outputs declaration to version-and-publish job
- Exposed new-version, current-version, and version-type outputs
- Fixed notify-success job to properly reference outputs
- Added conditional check to prevent empty version notifications

### Additional Improvements
- Enhanced lockfile handling for both package-lock.json and pnpm-lock.yaml
- Added --no-git-checks flag to pnpm publish for CI environment
- Improved success notification with version change details
