feat(run): .NET project run and debug configurations (#686)

.NET projects had no run configurations.

Projects from .csproj files (and those listed in .sln/.slnx) now get configurations: executable projects (OutputType Exe/WinExe, or the Web SDK) get a .NET Project configuration running dotnet run, one per Project launch profile in Properties/launchSettings.json with its application URL and environment shown; test projects (Microsoft.NET.Test.Sdk) get dotnet test. The form edits project, target framework, launch profile, program arguments and environment, which override the profile's values. Debug builds the project, resolves the output assembly through MSBuild and launches it under netcoredbg, offering to install netcoredbg when missing. The source-text catalog test now ignores Rust character literals when collecting backend strings.
