macOS 自带 bash 3.2 在 set -eu 下对 `local var=$(cmd)` 有已知坑,
升级模式跑到 'Checking config health' 时报 `backup?: unbound variable`
(line 1169 cp $backup).

修法:
- backup 在函数顶部预绑定为空串 (local need_place=0 reason="" backup=""),
  永不 unbound
- 后缀改用 $$.${RANDOM:-0} (始终有值、无命令替换), 弃用 $(date +%s ...)
- 消除 local-带-命令替换 模式, bash 3.2/5 通用
