I'm noticing local branches just stick around.

I'm noticing local branches just stick around. I'm not sure what my workflow is supposed to be. I do a task in the worktree, have it merged, and archive the chat. I have instructions that say to delete the local branch when finished, but it can't because the worktree is still live (presumably until I archive it?)

从 /chat 工作流开始，复现报告中的操作序列：在 worktree 中完成一项任务，执行 merge，然后归档聊天。跟踪 worktree 和本地分支何时被释放，然后检查相关的现有测试或生命周期入口点。完成的标准是预期的清理行为明确，并且工作流完成后本地分支不再意外保留。
