//! `loft record-install <way>`: records how this executable was installed, for the update notice
//! and the command event. The npm package runs it from its install script, so a record that
//! cannot be written is told on standard error and still exits 0: an install never fails
//! because of it. It reads no tree, sends no event and asks GitHub nothing.
