Historically, running `create_github_release --publish-release` would
always publish a new release from latest `main`, which isn't always the
best idea. We should really publish an alpha, let it bake, and then
promote it.
This PR introduces a new flag, `--promote-alpha`, which does exactly
that. It also works with `--dry-run`, so you can sanity check the commit
it will use as the base commit for the new release before running it for
real.
```shell
$ ./codex-rs/scripts/create_github_release --dry-run --promote-alpha 0.56.0-alpha.2
Publishing version 0.56.0
Running gh api GET /repos/openai/codex/git/refs/tags/rust-v0.56.0-alpha.2
Running gh api GET /repos/openai/codex/git/tags/7d4ef77bc35b011aa0c76c5cbe6cd7d3e53f1dfe
Running gh api GET /repos/openai/codex/compare/main...8b49211e67d3c863df5ecc13fc5f88516a20fa69
Would publish version 0.56.0 using base commit 62474a30e8 derived from rust-v0.56.0-alpha.2.

npm i -g @openai/codex

Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager. If you use npm:
npm install -g @openai/codex
Alternatively, if you use Homebrew:
brew install --cask codex
Then simply run codex to get started:
codex
If you're running into upgrade issues with Homebrew, see the FAQ entry on brew upgrade codex.
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
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
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.
