fix(all): refactor nested ternary expressions for readability (~20 instances)

Problem

All framework packages have no-nested-ternary warnings. Nested ternaries are hard to read and error-prone.

Affected files

Antd

• caveat.tsx, expand.tsx (x2), madlibs.tsx, prompt-details.tsx, sample-response.tsx, synthesis.tsx, verification.tsx

Bootstrap

• caveat.tsx, expand.tsx (x2), madlibs.tsx, prompt-details.tsx, sample-response.tsx, synthesis.tsx, verification.tsx

Mantine

• action-list.tsx, follow-up.tsx, inline-action.tsx, prompt-details.tsx, restyle.tsx, templates.tsx

Fix

Extract nested ternaries into named variables, helper functions, or use early-return patterns:

- const color = isActive ? 'blue' : isDisabled ? 'gray' : 'black'
+ const getColor = () => {
+   if (isActive) return 'blue';
+   if (isDisabled) return 'gray';
+   return 'black';
+ };
+ const color = getColor();

Count

~20+ instances.
