## Title

    Proposed fix: [Claude Code npm] 'Could not find native binary package "@anthropic-ai/claude-code-darwin-arm64"' — x64 Node under Rosetta 2 on Apple Silicon (darwin-x64 binary needs AVX)

## Body

    Recommended action: Install an arm64 Node and reinstall Claude Code (the wrapper suggests `arch -arm64 zsh -c "nvm install --lts && npm i -g @anthropic-ai/claude-code"`).
    
    Option: Install an arm64 Node and reinstall Claude Code (the wrapper suggests `arch -arm64 zsh -c "nvm install --lts && npm i -g @anthropic-ai/claude-code"`). [evidence: official_recommended_action]
    Applies when: Installing/running Claude Code via npm with an x64 Node on Apple Silicon
    Steps:
    1. Check `node -p process.arch` — x64 on an M-series Mac means Rosetta Node.
    2. Install arm64 Node (e.g. under `arch -arm64`).
    3. Reinstall @anthropic-ai/claude-code globally.
    Expected: The error no longer appears.
