At the base it's because meson wants to use @rpath, see
https://github.com/mesonbuild/meson/issues/3574. This led to
https://gitlab.gnome.org/GNOME/gobject-introspection/issues/222.
Running in a jhbuild shell should get DYLD_LIBRARY_PATH set for you and that
should get dlopen() to load the libraries/modules with basename-only paths in
foo.typelib.
For your bundle,
https://gitlab.gnome.org/GNOME/gtk-mac-bundler/commit/93edee7e2d0ec8230aaf5acb21452202b10cd678
is supposed to fix the paths in the Gir files to be
@excutable_path/../Resources/lib/foo.dylib and then recompile the type libs. If
you're sure you've got that commit and it's not working then we need to figure
out why not.

John Ralls
