The update-manpages wrapper calls update_manpages.main() unconditionally. With spawn and forkserver, multiprocessing re-executes the directly run main script as __mp_main__. The wrapper then calls main() again and tries to create another Pool while the child is still starting. Protect the entrypoint with __main__ guard. On Linux, this was mostly hidden while fork was the default start method; Python 3.14 now defaults to forkserver there. Normal command-line behavior is unchanged. Add a regression test that mirrors multiprocessing's __mp_main__ execution path and checks that it does not call update_manpages.main().
