Crash when ~/.pyenv directory doesn't exist: ENOENT in sandbox setup #45

open-codex crashes with ENOENT: no such file or directory when the ~/.pyenv directory
doesn't exist on the system.

Environment

• open-codex version: 0.1.31
• Node.js: v22.21.1
• OS: macOS (arm64)

Error

Error: ENOENT: no such file or directory, lstat '/Users/username/.pyenv'
at realpathSync (node:fs:2786:29)
at file:///.../open-codex/dist/cli.js:410:3516
at Array.map ()
at Yae (file:///.../open-codex/dist/cli.js:410:3425)

Root Cause

In cli.js, the YRe() function returns a hardcoded list of directories including
~/.pyenv:

function YRe(){return[Ef,`${process.env.HOME}/.pyenv`]}

These paths are then passed to realpathSync() without checking if they exist:

param:`-DWRITABLE_ROOT_${E}=${HRe(A)}`  // HRe = realpathSync

This crashes if .pyenv is not installed on the system.
