fix(code-mode): hide Codex's native console window on Windows

Codex's engine ships as a native console-subsystem binary (codex.exe). Launched
from our console-less Electron process tree, Windows allocated a fresh *visible*
console window for it; closing that window wedged the run in a pending state.
(Claude Code is a Node CLI, so it never triggers this.)

The window is created by @openai/codex's launcher (bin/codex.js), which spawns
codex.exe with no windowsHide. Patch it via pnpm to pass windowsHide: true
(CREATE_NO_WINDOW) so the console stays hidden — no window, nothing to close.
