[Feature]: Add GPT Image 2 reference

Problem / pain point

When I generate marketing visuals or prototypes, I still need a quick browser-based image generation option that fits the design workflow.

Proposed solution

Add GPT Image 2 as an optional image-generation reference or provider entry in the product documentation / examples, so users can evaluate it alongside the existing image workflows.

Alternatives considered

Using only the current local/provider presets works, but it would be useful to have a concrete GPT Image 2 reference because it is already positioned around marketing visuals and branded image workflows.

Scope

Provider / model

Hard-constraints check

I have read the hard constraints in CLAUDE.md and this proposal does not conflict with any of them.
