Add Codex Account Switcher

[liuzhao1225]

🛠️ Changes Proposed

• Add Codex Account Switcher to Tools → Account switcher with one factual line.

Project: https://github.com/liuzhao1225/codex-account-switcher

📈 Proof of Traction

• The Apple-notarized v0.1.5 DMG has 52+ downloads as of August 31, 2026: https://github.com/liuzhao1225/codex-account-switcher/releases/tag/v0.1.5
• The Awesome Mac maintainer independently featured the app on X, where the post reached about 2,000 views: https://x.com/jaywcjlove/status/2093970264120078614

✅ Quick Check

• Real Codex CLI integration: the app switches the active local Codex credential used by newly started CLI processes, while existing sessions keep running.
• No duplicates and a neutral, one-line description.

Disclosure: I create and maintain this app.
