zsol-openai 39a2438d16 Prefer releases.openai.com in standalone installers (#34910) ...

## What changed

- Make the shell and PowerShell installers download release metadata and assets from `releases.openai.com` by default, with bounded request timeouts.
- Fall back to GitHub Releases when metadata is unusable, required assets are missing, or downloaded assets fail checksum or manifest validation.
- Document `CODEX_INSTALLER_USE_RELEASES_OPENAI_COM=false` for opting out of the default release source.

## Testing

- Cover default-source installation, malformed and incomplete metadata, version mismatches, corrupt assets, invalid checksums, incomplete manifests, and GitHub fallback failures in the shell installer tests.
