. Add quiz question feedback customization

[DeFiVC]

What: Allow quiz questions to include custom feedback text for correct and incorrect answers, rather than generic "Correct!" / "Incorrect" messages.

Why: Generic feedback doesn't help users learn. Custom feedback explaining why an answer is correct/incorrect improves the learning experience significantly.

Scope: Add optional correctFeedback and incorrectFeedback fields to quiz questions. Use these in QuizService.submitQuiz when generating feedback text. AI service should generate these fields.

Acceptance criteria:

• Questions can have custom feedback per answer
• Custom feedback is used in submission results
• Falls back to generic feedback if not provided
• AI service generates feedback when creating quizzes

Technical context: src/modules/quizzes/quiz.service.ts:249-261 — feedback generation. src/modules/quizzes/quiz.types.ts — QuizQuestion interface.

Hi Maintainer, I’d like to take this issue up. I’ve reviewed the requirements and can work on adding the custom feedback fields, updating the quiz submission flow, and keeping the existing generic feedback as a fallback.

I’ll also cover the AI-generated quiz questions and add the necessary tests. Please consider assigning it to me. Thank you.

Hello Maintainer, I’m interested in working on this task. Custom feedback should make the quiz results more useful, so I’d be happy to implement the question fields and wire them into the submission response.

I’ll make sure questions without custom feedback continue to use the current behaviour and test both cases. Kindly assign it to me if available.

Hi, I’ve gone through the issue and would like to contribute to it. I can handle the changes to the quiz question type, feedback generation, and AI quiz creation so that each answer can have a proper explanation.

I’ll also add coverage for the fallback behaviour to avoid breaking existing quizzes. I’d appreciate being assigned this task. Thank you.
