# tool-moyu.sh — AI「摸鱼」模拟器
#
# 作用：读取一段内容（默认本会话日志，或任意文件/stdin），
#       循环「假装在处理」，模拟 AI 工作的样子。
#       适合：需要看起来在干活、又不想真干活的时候 😏
#
# 用法:
#   ./tool-moyu.sh                  # 用内置内容摸鱼(默认)
#   ./tool-moyu.sh -n 3             # 循环 3 遍
#   ./tool-moyu.sh [文件]           # 从文件读取(覆盖内置内容)
#   ./tool-moyu.sh --help           # 帮助
#
# 选项:
#   -n N      循环 N 次（默认无限）
#   -d MS     每行间隔毫秒（默认随机 80-400）
#   -t        逐个字符「打字」效果
#   -s        静默模式：不打印假状态行，只循环内容
