feat: Created agent config generator for the onboarding flow

[AshAnand34]

Issue: #391

Summary

I've created a comprehensive agent config generator that can be used in an onboarding flow. Here's what was implemented:

🏗️ Two-Node Agent Config Generator

First Node - Generate Agent Fields:

• Analyzes user inputs from the onboarding form
• Uses intelligent logic to generate appropriate agent configurations based on:
  • Use case description
  • Industry context
  • Primary tasks
  • Tools needed
  • Model preferences

Second Node - Create Agent Configuration:

• Combines generated fields into a complete agent configuration
• Includes system prompts, model settings, tool recommendations, and RAG configuration

📋 Onboarding Flow Components

Multi-step Form (/onboarding):

1. Welcome Screen - Introduces the platform and guides users through the process
2. Step 1 - Basic information (use case, industry, company size)
3. Step 2 - Tasks and capabilities (specific tasks, tool selection)
4. Step 3 - Advanced configuration (model selection, RAG, budget)

Success Screen - Shows the generated agent configuration and allows users to create it

🔧 Key Features

• Intelligent Agent Generation: The system analyzes user inputs and creates tailored agent configurations
• Smart Defaults: Automatically selects appropriate models, tools, and settings based on use case
• Flexible Configuration: Supports all major agent types (standard, tools, RAG, supervisor)
• User-Friendly Interface: Clean, step-by-step onboarding experience
• Integration Ready: Connects with existing agent creation system

🚀 Integration Points

• API Route: /api/onboarding/create-agent handles the backend processing
• Navigation: Added "Guided Setup" button to the agents page
• Agent Creation: Seamlessly integrates with existing agent creation workflow

The implementation follows the existing codebase patterns, uses shadcn/ui components, and integrates seamlessly with the current agent management system. Users can now create their first agent through an intuitive guided process that automatically generates appropriate configurations based on their specific needs.
