## Title

    Proposed fix: [Claude Code sandbox] 'Sandboxing requires WSL2' — /sandbox unavailable on WSL1 (and native Windows); commands run unsandboxed unless failIfUnavailable

## Body

    Recommended action: Upgrade the distro to WSL2 (or run without sandboxing); set sandbox.failIfUnavailable for managed deployments that require it.
    
    Option: Upgrade the distro to WSL2 (or run without sandboxing); set sandbox.failIfUnavailable for managed deployments that require it. [evidence: official_recommended_action]
    Applies when: Enabling /sandbox on WSL1 or native Windows
    Steps:
    1. Run `wsl -l -v` in PowerShell
    2. `wsl --set-version <distro> 2`
    3. Install bubblewrap and socat inside WSL2
    4. Set sandbox.failIfUnavailable: true where sandboxing is mandatory
    Expected: The error no longer appears.
