Windows 的 ninja 目标带 .exe;以及 strip 回答的比预期少

⚠️ ninja: error: unknown target 'qemu-system-x86_64' —— meson 按它产出的文件命名
目标,所以 Unix 那几条腿写不带后缀的名字,这一条要带。

⭐ **strip 之后的数字说明 316MB 根本不是模拟器。** linux-x64 实测:二进制
78.7MB → 27.0MB,而整个前缀 392MB → 343MB。一个把这个前缀直接打包的载荷会把那
316MB 一起发出去 —— 而索引的资产预算是实测 0.012 MB/s 的单连接上传、无分片、无
断点续传,所以**载荷选什么**比它 strip 掉什么更重要。

先列出来而不是先删:模拟器运行时到底需要其中哪些是描述符要回答的问题,而靠「删到
出问题为止」来回答,正是一个载荷在别人机器上少一个固件 blob 的由来。
