For every non-debug run, it should check for changes in files, perhaps
by comparing the mtime of the packed file against all of the files it
would contain. However, that begs the question of what happens in an
installed instance, where the user running it likely doesn't have
permissions to re-pack the files if they're in the installation
directory. Perhaps packing should be done into a temp directory for
each user?

For debug runs, it should use the unpacked files in each module.

That's the intention, yes. It could be that the installer would
re-pack everything by calling a script we can supply, or the mechanism
I suggested above could handle it on next launch.

I'm actually thinking that maybe it would be easier to start with the
CSS files....
