Research direction
Start at windows/updater/Updater.cs:173-200 where DownloadOne writes cache/<sha256>.zip, and note that only the .part file is deliberately kept for resume. Then read windows/updater/Program.cs:82 to find where a download is declared installed — that is the point after which the finished ZIP can be deleted (or pruned to the last N). Finish by adding a sentence to docs/自动更新.md; done means the installed package's ZIP is gone while .part resume files still behave as before. Verify by two consecutive update installs and inspecting %LOCALAPPDATA%\BirdLock\updates\downloads.

Description
位置：windows/updater/Updater.cs:173-200；windows/updater/Program.cs:82
现象：DownloadOne 把完成包存成 cache/<sha256>.zip，成功后没有任何删除或修剪。.part 保留是续传需要，但完整 ZIP 在安装成功后已无用，每轮大版本更新都会在 %LOCALAPPDATA%\BirdLock\updates\downloads 留下数百 MB。
复现：连续两次安装更新后查看该目录。
建议：安装成功后删除对应 cache/<sha256>.zip，或只保留最近 N 个；docs/自动更新.md 也补一句说明。
