Running OpenAI Codex CLI in Termux (Android, aarch64)

Problem

• The official npm package (@openai/codex) ships prebuilt binaries (codex-aarch64-unknown-linux-musl).

• Android’s Bionic libc rejects them with:

  error: "…/codex-aarch64-unknown-linux-musl" has unexpected e_type: 2

• Result: the CLI doesn’t launch in Termux.
