Subject: [PATCH] fix(sdk): exclude template folders from default compilation

Template files contain VS template placeholders ($safeprojectname$, etc.)
that are not valid C# and should not be compiled as part of the extension.

This adds ProjectTemplates/** and ItemTemplates/** to DefaultItemExcludes.
