Currently, our `npm publish` logic is failing.
There were a number of things that were merged recently that seemed to
contribute to this situation, though I think we have fixed most of them,
but this one stands out:
https://github.com/openai/codex/pull/10115
As best I can tell, we tried to fix the pnpm version to a specific hash,
but we did not do it consistently (though `shell-tool-mcp/package.json`
had it specified twice...), so for this PR, I ran:
```
$ git ls-files | grep package.json
codex-cli/package.json
codex-rs/responses-api-proxy/npm/package.json
package.json
sdk/typescript/package.json
shell-tool-mcp/package.json
```
and ensured that all of them now have this line:
```json
"packageManager": "pnpm@10.28.2+sha512.41872f037ad22f7348e3b1debbaf7e867cfd448f2726d9cf74c08f19507c31d2c8e7a11525b983febc2df640b5438dee6023ebb1f84ed43cc2d654d2bc326264"
```
I also went and deleted all of the `corepack` stuff that was added by
https://github.com/openai/codex/pull/10115.
If someone can explain why we need it and verify it does not break `npm
publish`, then we can bring it back.
This PR expands `.github/workflows/rust-release.yml` so that it also
builds and publishes the `npm` module for
`@openai/codex-responses-api-proxy` in addition to `@openai/codex`. Note
both `npm` modules are similar, in that they each contain a single `.js`
file that is a thin launcher around the appropriate native executable.
(Since we have a minimal dependency on Node.js, I also lowered the
minimum version from 20 to 16 and verified that works on my machine.)
As part of this change, we tighten up some of the docs around
`codex-responses-api-proxy` and ensure the details regarding protecting
the `OPENAI_API_KEY` in memory match the implementation.
To test the `npm` build process, I ran:
```
./codex-cli/scripts/build_npm_package.py --package codex-responses-api-proxy --version 0.43.0-alpha.3
```
which stages the `npm` module for `@openai/codex-responses-api-proxy` in
a temp directory, using the binary artifacts from
https://github.com/openai/codex/releases/tag/rust-v0.43.0-alpha.3.
