r'''统一清理两个平台发行版里的重复附件。

背景：
    重发时如果只"复用已有发行版"，附件会一次次堆积。
    Gitee 尤其绕：`GET /releases/tags/{tag}` 返回的 `assets`
    **只有 name 和 download_url，没有 id**，所以没法删。
    但另一个接口有 id：
        GET    /repos/{o}/{r}/releases/{id}/attach_files  -> 带 id
        DELETE /repos/{o}/{r}/releases/{id}/attach_files/{attach_id}

    Gitea/EzHub 则直接有 assets[].id。

策略：同名附件只保留最新的一份，其余删掉。
支持 --dry 先看要删什么。
