Subject: [PATCH] feat(bin): support bun fallback runtime for codex CLI (#282)

This PR adds a shell wrapper in `codex-cli/bin/codex` to detect node or
bun as the runtime.

It updates:
- `package.json` bin entry
- published files list to include bin/
- README install instructions to include `bun install -g @openai/codex`
