codex-package archives bundle stale codex-zsh manifest

What happened?

scripts/codex_package/codex-zsh is the DotSlash manifest used by the release package layout for bundled zsh support. The checked-in manifest currently points at rust-v0.134.0-alpha.3 assets.

The latest rust-v0.135.0 release publishes fresh codex-zsh-* assets as well as codex-package-* archives, but the package builder still reads the checked-in manifest. That means generated codex-package-* archives can bundle a codex-zsh manifest pinned to the older alpha release instead of the matching release assets.

Expected behavior

The codex-zsh manifest bundled into codex-package-* archives should be updated to the current release assets as part of the release/package process, or the package builder should generate/select a manifest matching the release being packaged.

Additional context

I searched open issues and PRs for terms including codex-zsh, codex-package, stale release package, and manifest staleness, and did not find an existing open item that appears to cover this release packaging mismatch.
