Fix CI for single net8.0 DLL structure

- Build only PowerShell.MCP module, let dotnet test handle its own restore+build
- Move SelfContained from Proxy csproj to publish command line
- Add --self-contained to Build-AllPlatforms.ps1 publish args
- Exclude Proxy test files on net8.0 (Proxy is net9.0 only)
- Make path tests cross-platform (skip Windows drive-letter tests on Unix)
