/**
 * Regression test for bug #3562 — Codex global install must create a
 * discoverable $gsd-* skill surface.
 *
 * Codex CLI 0.130.0 (the version in the issue report) does NOT auto-discover
 * commands from get-shit-done/workflows/*.md or agents/*.md. It only registers
 * commands from skills/<name>/SKILL.md. Prior installer logic ("Codex now
 * discovers official skills from .agents/skills") was based on an assumption
 * that does not match the shipping Codex CLI behavior, leaving users with
 * workflows on disk and no $gsd-* entrypoints after `npx get-shit-done-redux
 * --codex --global`.
 *
 * Fix: re-wire copyCommandsAsCodexSkills() back into the install dispatch path
 * so the same skill-shape that Claude / Copilot / Antigravity / Cursor /
 * Windsurf / Augment / Trae installs produce is also produced for Codex.
