Debian 11 / Ubuntu 22.04 的库包是 libassimp5，Debian 12+ 才是 libassimp6； 写死库名会让 apt 报 'no installation candidate'，自动安装直接失败。 改为只装 assimp-utils（它按发行版依赖对应的库版本）。

* Assimp 缺失时的可诊断性。

||
*
|
||
* 背景（真实故障）：服务器没装 Assimp，上传 PMX 压缩包只得到
|
||
* GLB 直出：导出失败（ENOENT）：spawn assimp ENOENT
|
||
* glTF 直出：导出失败（ENOENT）：spawn assimp ENOENT
|
||
* 用户看不出「缺什么、怎么装」。现在：
|
||
* * 转换前先定位二进制，找不到就一次性给出安装命令与查过的路径；
|
||
* * 定位逻辑覆盖 PATH 之外的常见目录（服务由 systemd 托管时 PATH 可能很窄）。
