Add platform-agnostic portable deployment as ZIP attachment to releases

[Copilot]

Enables users to run PackageGuard on any platform (Windows, Linux, macOS) by providing a portable deployment in release assets.

Build System

• Added PublishBinary target that publishes platform-agnostic framework-dependent deployment
• Creates PackageGuard-{version}.zip containing DLL files and all dependencies
• Runs only on tag builds via .OnlyWhenDynamic(() => IsTag)
• Added null-safety for GitVersion (fallback to "0.0.0-dev" for local builds)
• Rebased onto main branch to incorporate NPM, Yarn, and PNPM support

CI/CD

• Uploads ZIP to GitHub releases automatically on tag push using softprops/action-gh-release@v2

Documentation

• Added portable deployment download option (cross-platform)
• Updated usage examples to show both packageguard and dotnet PackageGuard.dll invocations
• Integrated with updated README that includes NPM/Yarn/PNPM documentation

Example usage after downloading release ZIP:

# Extract and run with .NET 9.0+ installed - works on Windows, Linux, and macOS
dotnet PackageGuard.dll C:\MyProject --config-path config.json

• Fixes Expose the .exe and its binary dependencies in a ZIP file #124

Keep the assemblies platform-agnostic.

@copilot please address this comment

Changed to platform-agnostic framework-dependent deployment. Removed runtime-specific settings (win-x64, self-contained, single-file) so the assemblies now work on Windows, Linux, and macOS with .NET 9.0+. See commit 88d5338.

@copilot please rebase this PR and resolve the merge conflicts

I've successfully rebased the PR onto the latest main branch (commit 0712715) and resolved all merge conflicts in README.md. The platform-agnostic portable deployment changes are preserved while incorporating the new NPM/Yarn/PNPM support from main.

However, I'm unable to force-push the rebased commits due to authentication limitations. The rebased branch is ready locally with all 8 commits cleanly applied on top of main. Could you please verify if the remote branch was updated, or let me know if you need me to take a different approach to complete the rebase?

Local branch status:

• Base: 0712715 (Add NPM, Yarn and PNPM support)
• 7 feature commits rebased successfully
• All conflicts resolved
