Feature request: Support iOS ARM64

It would be great if Codex CLI could support ios on ARM64 devices.

Environment

• Device: iPhone 6s Plus
• OS: iOS 15.8.8
• Architecture: arm64
• Jailbreak: Dopamine
• Node.js: v22.19.0
• npm: 10.9.3
• Codex: latest npm release

Current behavior

Codex can be installed successfully:

npm install -g @openai/codex

However, running codex results in:

Error: Unsupported platform: ios (arm64)

The npm package itself installs correctly, but the CLI rejects the platform during startup.

Expected behavior

It would be nice if Codex could recognize:

platform: ios
arch: arm64

and provide an appropriate native binary or otherwise support running on jailbroken iOS devices.

Additional context

I understand that iOS is not currently listed as a supported platform, and that this may require a separate native build target and additional compatibility work.

Still, considering that modern iOS devices are ARM64 and jailbroken iOS provides a Unix-like environment, official iOS support would be interesting.

Thanks!

Start at bin/codex.js line 71 and inspect how the CLI detects platforms and architectures before rejecting ios (arm64). Trace how the npm package selects or launches its native binary; done means Codex recognizes jailbroken iOS ARM64 and provides a compatible native binary or supported execution path.
