Cannot install opencode-ai globally via yarn or npm

Description

When installing opencode CLI globally via yarn global add opencode-ai on Windows, the postinstall script fails with exit code 1. The error message says:“It seems your package manager failed to install the right opencode CLI package. Try manually installing 'opencode-windows-x64' or 'opencode-windows-x64-baseline'.”
I have already run npm cache clean --force and retried, but the issue persists. Expected successful installation, but it aborts with the above error.
Environment:

• OS: Windows 11 (or 10)
• Node.js: v20.11.0 (replace with your version)
• yarn: 1.22.22
• Package manager: yarn global
