修 Gitee 附件清理：assets 字段没 id，要用 attach_files 接口

Gitee 的坑：GET /releases/{id} 返回的 assets 里
**只有 name 和 download_url，没有 id**，
照着它删是删不掉的（之前静默失败，附件一路堆到 11 个）。

必须换接口才拿得到 id：
    GET    /releases/{id}/attach_files        -> [{id, name, size}]
    DELETE /releases/{id}/attach_files/{id}

已清理：Gitee 11 -> 5 个（含 2 个自动生成的源码包），
EzHub 5 -> 3 个。清理动作也加了重试（网络会抖）。

+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。
