does the subroutine "bar" run every time I put use Model::Conf in other packages?

If you use or require the module, Perl keeps tracks of already loaded modules (in %INC), so the code is loaded/compiled/executed only once.

(do EXPR also adds an entry in %INC, but doesn't check itself before loading, so with do the module's code would be executed several times.)
