+/**
+ * 清理一个 feature 分支（远程 + 本地），供「拖到完成」和「手动删除 worktree」两处共用。
+ *
+ * - 受保护分支（main/master/devBranch/autoBuildBranch）直接跳过，绝不删。
+ * - 远程删除走 gitea API，需 remote + token；缺任一则只删本地，不阻断。
+ * - 本地删除是强删（deleteLocalBranch 内部 `git branch -D`）：调用方语义是「连分支一起删」，
+ *   未合并也照删。
+ * - 全程 best-effort：远程 / 本地各自 try/catch，失败只记日志——分支清理从不回滚已完成的主流程
+ *   （worktree 已删、PR 已合并）。branch 为空直接返回。
+ *
+ * 放在 handlers 层而非 `git/branchSync.ts`：后者刻意不依赖 `vscode`（有单测覆盖
+ * deleteLocalBranch），而本函数要用 logger（→ vscode）和 gitea API。
