Michael Bolin e39ddc61b1 bazel: add Windows gnullvm stack flags to unit test binaries (#16074)
## Summary

Add the Windows gnullvm stack-reserve flags to the `*-unit-tests-bin`
path in `codex_rust_crate()`.

## Why

This is the narrow code fix behind the earlier review comment on
[#16067](https://github.com/openai/codex/pull/16067). That comment was
stale relative to the workflow-only PR it landed on, but it pointed at a
real gap in `defs.bzl`.

Today, `codex_rust_crate()` already appends
`WINDOWS_GNULLVM_RUSTC_STACK_FLAGS` for:

- `rust_binary()` targets
- integration-test `rust_test()` targets

But the unit-test binary path still omitted those flags. That meant the
generated `*-unit-tests-bin` executables were not built the same way as
the rest of the Windows gnullvm executables in the macro.

## What Changed

- Added `WINDOWS_GNULLVM_RUSTC_STACK_FLAGS` to the `unit_test_binary`
`rust_test()` rule in `defs.bzl`
- Added a short comment explaining why unit-test binaries need the same
stack-reserve treatment as binaries and integration tests on Windows
gnullvm

## Testing

- `bazel query '//codex-rs/core:*'`
- `bazel query '//codex-rs/shell-command:*'`

Those queries load packages that exercise `codex_rust_crate()`,
including `*-unit-tests-bin` targets. The actual runtime effect is
Windows-specific, so the real end-to-end confirmation still comes from
Windows CI.

npm i -g @openai/codex
or brew install --cask codex

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

Codex CLI splash


If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.


Quickstart

Installing and running Codex CLI

Install globally with your preferred package manager:

# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex

Then simply run codex to get started.

You can also go to the latest GitHub Release and download the appropriate binary for your platform.

Each GitHub Release contains many executables, but in practice, you likely want one of these:

  • macOS
    • Apple Silicon/arm64: codex-aarch64-apple-darwin.tar.gz
    • x86_64 (older Mac hardware): codex-x86_64-apple-darwin.tar.gz
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
