gx10 fail при первой установке (фото юзера 2026-05-18): jq: error: Could not open file /home/keisei/.claude/settings.json [error] jq-merge produced invalid output; ... unchanged [error] install failed at line 126; rolled back Root cause: backup_file() (install/lib-backup.sh:56) делал `mv target backup`, затем activate_hooks() → _jq_merge_hooks() пыталась читать оригинал target'а через jq — но оригинал уже унесён mv'ом, открыть нечего. jq fail → rollback всей установки. Fix: cp -a вместо mv (как уже сделано в backup_path() для директорий). Атомарный безопасный бэкап; оригинал остаётся для jq, потом _jq_merge_hooks атомарно переписывает его mv tmp → target.
