What issue are you seeing?

The zsh completion script generated by codex completion zsh does not provide suggestions for profiles defined in config.toml.

What steps can reproduce the bug?

1. Define a profile in ~/.codex/config.toml:

``toml
[profiles.my-profile]
model = "gpt-4o"
``

1. Type codex -p and press Tab.

What is the expected behavior?

Zsh should suggest the available profiles (e.g., my-profile) instead of falling back to default filename completion.

Analysis shows the generated _codex script uses _default for the CONFIG_PROFILE argument:
'-p+[Configuration profile from config.toml to specify default options]:CONFIG_PROFILE:_default'
