Replace editbin postbuild with GuardCF task

Browse Source 
Reworked the post-build CFG handling in `Brovan.csproj` by replacing the Windows batch `editbin.exe` flow with an inline MSBuild `RoslynCodeTaskFactory` task (`DisableGuardCF`). The new task directly edits the built `.exe` PE header to clear the GuardCF bit when present, removing the dependency on VsDevCmd/editbin availability.
