A socket path too long for sun_path leaves no listener and the editor's turn untouched: the GUI no longer calls into a freed one at startup

listen started the editor's turn and pointed its answer_held and wake_parked hooks at the new Listener, then, when socketPath found the path too long for sun_path (108 bytes), freed the Listener with gpa.destroy while the hooks stayed set; the GUI's next rest (waitInput) called answerHeld on freed memory and died with SIGSEGV. The lapis bench's runs crashed for 12-character names in an 82-byte runtime directory (a 110-byte path) and not for shorter ones. The path is checked before anything is made; a unit test asks listen for a name too long and finds the turn's hooks clear and the turn not started.
