✨ feat(vscode): 手动删除 worktree 时连同 feature 分支一起删（本地+远程）

抽出共享 cleanupFeatureBranch（handlers/branchCleanup.ts）：受保护分支跳过、
远程走 gitea API、本地强删（git branch -D），全程 best-effort 只记日志。
「拖到完成」的分支清理改为复用它（71 行 → 12 行）；handleDeleteWorktree 在
删完 worktree 目录后同样调用它，确认框与完成提示带上分支名。

放在 handlers 层而非 git/branchSync.ts：后者刻意不依赖 vscode（有单测覆盖
deleteLocalBranch），本函数需 logger（→vscode）+ gitea API。
