feat: add user requirements analysis feature in chat mode

🎯 Overview

Adds intelligent requirement gathering to chat interface - AI generates targeted questions to help users provide more detailed project requirements before code generation.

✨ Key Features

• Guided Analysis Mode: AI asks 5-8 smart questions based on user's initial input
• Flexible Interaction: Users can answer, skip, or provide partial responses
• Smart Question Generation: Context-aware questions for web apps, data analysis, ML projects
• Structured Output: AI synthesizes answers into comprehensive requirement documents

🔧 Implementation
