Package codex-cli without vendored binary

The install phase installs dependencies with pnpm install --ignore-scripts and only copies bin/codex.js into $out/bin. The CLI immediately tries to spawn vendor/<target>/codex (see bin/codex.js), but no vendor directory is produced or installed here—--ignore-scripts prevents any postinstall steps that might fetch the binary, and nothing builds or bundles codex-rs. Running nix build or nix run for this package will therefore fail at runtime with ENOENT because the expected native binary is missing. The derivation should build or link the codex binary into the output instead of packaging just the wrapper script.

Useful? React with 👍 / 👎.
