# Detach HEAD 释放 refs/heads/<default-branch> 这个本地分支名。
# 背景：claude-code-action 在 fork PR 上会执行
# git fetch origin pull/<n>/head:<head-ref-name>
# 把 PR head 拉到与 fork 端 head 同名的本地分支。当 fork PR 的 head ref
# 与本仓库 base / 默认分支同名（例如 fork 也是 beta → beta）时，
# 上面那条 fetch 会撞上"当前已 checkout 的分支"而失败：
# fatal: refusing to fetch into branch 'refs/heads/beta' checked out at ...
# 提前 detach 让本地分支名可以被 action 重新使用。
