Many permissive licenses (I'm specifically looking at MIT and BSD3) include a clause that the license file must be included in distributions of the source or the binary. It seems to me that if I have a project on Github, that qualifies as redistribution of the source. My questions are thus:

Do I need to include the license files from all my dependencies in my Github repository?

Does having them listed as dependencies in my .cabal file "implicitly" include them?

Does making a project "PublicDomain" only refer to the code contained in that project, or would it (unintentionally and unlawfully) give distributors of that source code the freedom to not include the BSD3/MIT license files from dependencies?

Essentially my goal is to waive all intellectual property rights to most of my Haskell projects, to the extent that, were I to unintentionally sign away my intellectual property, my open-source contributions would be safe - what's the easiest way to do this?

Thanks,
