fix: select the newest available ChatGPT model

[JJLiebig]

ChatGPT now shows GPT-6 instead of Latest, so ask-pro could not select a model and stopped before submission. Prefer the rolling Latest row when available; otherwise choose the highest numbered visible, enabled GPT model. Compare versions numerically so 5.10 beats 5.9, and keep Pro intelligence confirmation mandatory before sending.

Validation:

• 326 tests passed; build, lint/typecheck, formatting, package dry run, and plugin validation passed. The configured validator path is missing on this machine; validation used the bundled plugin-creator copy in harness-playground.
• Fast Review Suite rvw_e7b24eb3 completed with two clean signoffs. CodeRabbit found no actionable comments.
• Windows, macOS, and Linux CI passed on 693eb2b.
• Live, signed-in no-submit UI inspection confirmed visible enabled terminal GPT-6, GPT-5.6 Sol, and GPT-5.5 rows, GPT-6 checked, and Pro at 5/5.
• The optional full CLI smoke stopped at NEEDS_USER_AUTH before model selection; no prompt was submitted. That full smoke is waived for this change because it requires human login to the separate managed profile. The adapter behavior is covered locally and current picker controls were inspected live.

📝 Walkthrough

Walkthrough

The model picker now considers eligible numbered GPT models for the Latest target and selects the highest numeric version when needed. Tests and project documentation describe the fallback and the separate Pro intelligence requirement.
