Hot reload as a third launch mode, rewritten from dotnet-hot-reload

dotnet watch run with the startup project, configuration, platform and per-project launch options from the status bar. The debugger is no longer attached automatically: attach on demand, one notification with Re-attach when the watcher replaces the process. Rude edits follow a setting (restart / ask / warn). Warns before starting under an optimised configuration, which SDK 10's dotnet watch cannot hot reload. Solution build runs first so the Editor's post-build step finds the Builder.
