User story: So that I can use the intended Codex model choices from dev VMs, the VM package pinning and downstream defaults should track the Codex CLI version needed to expose them.

Part of the "Profiles & VM archetypes" arc.

The dev VM Codex install is pinned through vm.inputs.nixpkgs-unstable, then consumed by profiles as pkgs-unstable.codex.

Observed from a current dev VM:

Allod-pinned nixpkgs-unstable provides codex 0.142.2.
Current nixos-unstable provides codex 0.142.5.
codex doctor reports latest available CLI as 0.144.1.
The active model picker only lists gpt-5.5, gpt-5.4, and gpt-5.4-mini.

Need:

Decide whether updating only nixpkgs-unstable is enough once nixpkgs catches up, or add a narrow Codex package override in vm.
Rebuild a dev VM and verify codex --version, codex debug models, and the TUI model picker expose the latest intended model.
After the package supports it, update downstream profile defaults such as yolo codex --model ... in profiles.
