Function parseTaskAiOverrides

* Parse the optional `model`/`thinking` overrides supplied on a task launch, * reusing the exact parsing the UI uses (`normalizeModelInput` for model alias * resolution; `parseThinkingInput` for named levels OR numeric indices). Numeric * thinking indices stay deferred as a `ParsedThinkingInput`

(args: { model?: string | null; thinking?: string | null })

 * descriptive error on invalid input so the model can correct the call.
