/**
 * The pseudopotential file formats this build can read.
 *
 * Core seeds the registry with UPF on first use. A build-time add-on registers
 * its formats from its registration function, which every entry point runs
 * before it reads input (io/addon_registration.hpp). Formats are consulted in
 * registration order, so core's UPF is always asked first.
