zsol-openai 765675a122 Add an optional releases.openai.com installer source (#34514) ...

## What changed

- Let the shell and PowerShell installers resolve metadata and download assets from `releases.openai.com` when `CODEX_INSTALLER_USE_RELEASES_OPENAI_COM` is enabled.
- Fall back to GitHub Releases when metadata or asset downloads from the alternate source are unavailable.
- Verify that an installed or cached Codex binary reports the resolved version before activating it.

## Testing

- Cover latest-release installation, asset fallback, mismatched binary versions, and reuse of a cached legacy package in the shell installer tests.
