Bug: zsh: illegal hardware instruction on Intel Mac (x64)

Environment

• macOS Ventura 13
• Intel Mac (x64)
• Node v22.22.1 (nvm)
• process.arch = x64
• process.platform = darwin
• qmd 2.0.1
• Installed via: npm install -g @tobilu/qmd

Problem
Most qmd commands crash immediately with zsh: illegal hardware instruction:

$ qmd collection list
zsh: illegal hardware instruction  qmd collection list

$ qmd query scorecall
zsh: illegal hardware instruction  qmd query scorecall

Diagnosis
Both @node-llama-cpp/mac-arm64-metal and @node-llama-cpp/mac-x64 are present in node_modules. Despite process.arch correctly reporting x64, something is loading the arm64 binary at startup:

$ file .../node_modules/@node-llama-cpp/mac-arm64-metal/bins/mac-arm64-metal/llama-addon.node
Mach-O 64-bit dynamically linked shared library arm64

$ file .../node_modules/@node-llama-cpp/mac-x64/bins/mac-x64/llama-addon.node
Mach-O 64-bit dynamically linked shared library x86_64

Note: node-llama-cpp/dist/index.js loads fine in isolation:

$ node -e "import('...node-llama-cpp/dist/index.js').then(() => console.log('loaded ok'))"
loaded ok

But qmd crashes at startup before any JS output is produced, suggesting the arm64 binary is being loaded during module initialisation.

Workaround
NODE_LLAMA_CPP_SKIP_DOWNLOAD=true qmd --version works, but actual commands like qmd query and qmd collection list still crash.

Expected behavior
qmd should detect process.arch === x64 on darwin and load @node-llama-cpp/mac-x64 exclusively.
