fix package script to include hidden files (unless ignored)

[SillyFreak]

using * to move all files in a directory is faulty because * does not enumerate hidden files. use shopt -s dotglob to fix this

What sort of hidden files are you thinking of?

[SillyFreak]

Just in general. I was working on another new feature and noticed that top-level hidden files were ignored in general, independent of the Typst ignore. It's just for completeness, even if real packages would ordinarily not have any.

Fair fair :)
