Subject: [PATCH] Publish stable installer aliases to R2 (#34729)

## What changed

- Publish `install.sh` and `install.ps1` from stable release assets to the
  mutable `codex/install.sh` and `codex/install.ps1` R2 keys.
- Require both installer assets and verify each uploaded object's size,
  SHA-256 metadata, and CRC64 checksum before completing publication.
- Leave prerelease publication unchanged.
