worktree.sh

# =============================================
# Git Worktree 快速管理助手
# 用法：
#   ga <branch-name>     # 在平行目录创建新 worktree + 新分支，并自动 cd 进去
#   gd                   # 删除当前 worktree 和对应分支（带确认）
#
# 依赖：
#   - gum[](https://github.com/charmbracelet/gum) 用于美观的确认对话框
#   - mise (可选，如果你用 mise 管理工具版本)
