The PR is not yet safe to merge because the unresolved duplicate-question-ID finding can prevent users from answering independently.

Fix with agent prompt

### Issue 1
src/agent/tools/askQuestion.ts:10-14
The schema allows repeated question IDs, including an explicit ID that can collide with a generated `q_<index>` fallback. The card then uses each ID as both a Svelte list key and the key for its answer state. A call with duplicate IDs can fail to render or make separate questions share selections, preventing the user from answering them independently. Please enforce uniqueness after fallback IDs are assigned.

For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.

Summary

This PR adds an interactive clarification tool that lets agents pause execution, display multiple-choice questions in chat, and resume with the user's answers.

• Registers ask_question as an enabled built-in agent tool.
• Coordinates pending questions and answers through a reactive runtime store.
• Adds an interactive Svelte question card and completed-answer rendering.
• Exposes configuration controls and tests the tool and pending-question lifecycle.
• The completed-output validator now requires every selected answer to be a string.
