v0.120.0 missing Windows platform binaries (win32-x64, win32-arm64)

Bug Report

Summary

@openai/codex@0.120.0 fails to run on Windows because the platform-specific binary packages (0.120.0-win32-x64 and 0.120.0-win32-arm64) were not published to npm.

Environment

• OS: Windows 11 Pro (x64)
• Node.js: v24.12.0
• npm: latest

Steps to Reproduce

1. npm install -g @openai/codex@latest (installs 0.120.0)
2. codex --version

Error

file:///C:/Users/sunfl/AppData/Roaming/npm/node_modules/@openai/codex/bin/codex.js:100
    throw new Error(
          ^

Error: Missing optional dependency @openai/codex-win32-x64. Reinstall Codex: npm install -g @openai/codex@latest

Root Cause

The optionalDependencies in 0.120.0 reference:

"@openai/codex-win32-x64": "npm:@openai/codex@0.120.0-win32-x64",
"@openai/codex-win32-arm64": "npm:@openai/codex@0.120.0-win32-arm64"

However, these tagged versions were never published to the npm registry:

npm view @openai/codex-win32-x64
# 404 Not Found

Confirmed by checking published versions — 0.120.0-win32-x64 and 0.120.0-win32-arm64 are missing while Linux and macOS variants exist:

0.120.0-darwin-arm64  ✅
0.120.0-darwin-x64    ✅
0.120.0-linux-arm64   ✅
0.120.0-linux-x64     ✅
0.120.0-win32-arm64   ❌ missing
0.120.0-win32-x64     ❌ missing

Workaround

Downgrade to 0.119.0 which has all platform binaries published:

npm install -g @openai/codex@0.119.0

Expected Fix

Publish the missing 0.120.0-win32-x64 and 0.120.0-win32-arm64 tagged versions to npm, or release a patch version with the correct binaries.
