AskUserQuestion: render question bodies as markdown instead of all-bold text

Environment: Claude Code 2.1.211, macOS, terminal TUI.

What happens

The body of an AskUserQuestion renders entirely in bold in the terminal UI. Markdown inside it isn't rendered either: bullet lists show up as raw text lines, and **bold** markers can't be used to highlight anything because everything is already bold.

Why this matters more than it looks

We lean on AskUserQuestion heavily. Our system prompt requires the agent to end every turn with it: decisions go through it, status reports go through it, verification handoffs go through it. Part of the reason is a known gap where plain assistant text sent alongside or before the tool call is never displayed (#75182, #76760), so the question body is effectively the agent's only reliable channel to the user. That means bodies carry real content: a few lines of context, a bullet list of tradeoffs, sometimes a short status summary the user is asked to confirm.

Reading dozens of these a day, the all-bold rendering is the single biggest usability problem. Bold exists to make one thing stand out, and when the whole body is bold nothing does, so you can't skim a question, you have to read it linearly. For a tool whose entire job is getting a fast decision from a human, that's backwards.

What I'm asking for

Render question bodies as normal-weight markdown: regular text by default, formatted bullet lists, and **bold** reserved for what the author actually marked. Option descriptions would benefit from the same treatment.

That's the whole request. Happy to provide screenshots or test a build.
