Fix 75 Added AI assistant on the dashboard page

[unkeett]

🧠 Description

This PR introduces a minimal AI-powered assistant to the DevSync dashboard to enhance user engagement and provide productivity insights.

Backend

New route: /api/assistant

POST /message (JWT-protected): Returns a rules-based reply using user data such as streaks, goals, activity, and time spent. Placeholder for future LLM integration.

GET /nudge (JWT-protected): Returns motivational messages based on user streaks.

Mounted under general rate-limiting in server.js.

Controller logic in controllers/assistant.controller.js to compose user context.

Placeholders added for future LLM integration (services/llmService.js and services/insightsService.js).

Frontend

ChatBubble.jsx: Floating button at the top-right corner below the navbar.

ChatAssistant.jsx: Modal overlay with message list, input field, and API calls to backend endpoints.

Integrated into the Home page (src/App.jsx) with local state to handle open/close functionality.

Styling: Bubble positioned at top-24 right-6; modal uses h-[70vh] and scrollable content.

Next Steps

Integrate commit/problem tracking into backend models.

Enhance UX with typing indicators via Server-Sent Events or WebSockets.

Implement full LLM-based responses for dynamic assistant behavior.
