chmod can fail, preventing other files files from having their modes changed.

I use direnv and one of the things it does is create an immutable .direnv/ directory (or possibly it just creates links to the Nix store, which is immutable, I don't remember exactly) over which the current user does not have permissions. When newsite walks the file tree and tries to change the files' mode it fails on the first .direnv/ file it reaches

julia> newsite(".", template = "lanyon")
ERROR: IOError: chmod("/Users/<omitted>/.direnv/flake-profile-a5d5b61aa8a61b7d9d765e1daf971a9a578f1cfa", 0o644): operation not permitted (EPERM)

meaning that any files that are due to have their mode changed after that will be missed.

I think the "correct" fix here would be to only try to change the modes of files that are under Franklin's purview, but doing that properly in a way that is resilient to future changes is probably far more effort than it's worth. Instead I think a more pragmatic fix would be to either wrap the chmod call in a try or maybe allow the user to pass a list of paths to ignore when running it.

I also understand if you don't think this is a common enough problem to be worth maintaining a fix, since this is definitely a very niche issue.
