fix(models): Assimp 缺失时给出可操作报错，部署脚本自动安装
现象：服务器未安装 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，也不知道只传 glb/vrm 其实不需要它。 修复： 1. 新增 src/common/assimp.ts：按 ASSIMP_BIN -> PATH -> /usr/bin、/usr/local/bin 等常见目录定位可执行文件（只认文件，不认同名目录），转换前先预检； 找不到就一次性给出各发行版安装命令、查过的路径与替代办法， 不再打两条 ENOENT。动作预处理（FBX/glTF -> BVH）复用同一文案。 2. 新增 deploy/assimp-lib.sh：install.sh 按发行版自动安装 （apt-get / dnf / yum / zypper / apk / pacman），装在非常规目录时把绝对 路径写入 deploy/.env 的 ASSIMP_BIN；装不上只告警不中止，可用 SKIP_ASSIMP_INSTALL=1 跳过。check-access.sh 自检增加 Assimp 一行。 3. /health 增加 assimp.path；管理端「概览 -> 服务健康」显示 Assimp 状态， 不可用时给出安装提示。 4. 新增 test/assimp-locate.spec.ts 13 项；强化「assimp 不存在」用例断言安装命令。 测试规模 12 文件 / 193 项。 5. 版本 0.2.2，README(.md/.txt)/DSH.md 同步（前置要求、FAQ、环境变量说明）。
