Style of Publications chapter of PhD thesis
If the guidelines are flexible and your advisor has not provided you with specific guidance, then I think you can conclude that it really does not matter.  Including a list of your own publications is not a universal requirement for a thesis anyway.  Look at some past theses from students in your program, and  do something similar.

The reality would seem to be that it doesn't much matter how you format things.  If the thesis examiners want to look up your original publications, any format that makes them clear should be fine.  I have never had trouble looking at a student's original research papers, with or without a dedicated section listing them.
