Feature request: allow AskUserQuestion to render inline in the response text, not just as a modal

Currently, the AskUserQuestion tool always renders as a separate modal/widget above the input box — full-width stacked buttons, one per line, taking up a lot of vertical space regardless of how few/short the options are.

Request: support (or default to) an inline rendering mode, where the question and its options appear as part of the assistant's regular text response — e.g. as compact buttons or a small card grid within the message block — instead of a dedicated modal that pushes the input field down.

Motivation: for short questions with 2-3 options, a full-screen-width modal feels disproportionately large. An inline treatment (similar to how some chat UIs render quick-reply chips inside the message bubble) would keep the conversation visually compact without losing the structured-choice functionality.
