Major documentation overhaul: Transform to Python/FastAPI web application

This comprehensive update transforms Job Forge from a generic MVP concept to a
production-ready Python/FastAPI web application prototype with complete documentation,
testing infrastructure, and deployment procedures.

## 🏗️ Architecture Changes
- Updated all documentation to reflect Python/FastAPI + Dash + PostgreSQL stack
- Transformed from MVP concept to deployable web application prototype
- Added comprehensive multi-tenant architecture with Row Level Security (RLS)
- Integrated Claude API and OpenAI API for AI-powered document generation

## 📚 Documentation Overhaul
- **CLAUDE.md**: Complete rewrite as project orchestrator for 4 specialized agents
- **README.md**: New centralized documentation hub with organized navigation
- **API Specification**: Updated with comprehensive FastAPI endpoint documentation
- **Database Design**: Enhanced schema with RLS policies and performance optimization
- **Architecture Guide**: Transformed to web application focus with deployment strategy

## 🏗️ New Documentation Structure
- **docs/development/**: Python/FastAPI coding standards and development guidelines
- **docs/infrastructure/**: Docker setup and server deployment procedures
- **docs/testing/**: Comprehensive QA procedures with pytest integration
- **docs/ai/**: AI prompt templates and examples (preserved from original)

## 🎯 Team Structure Updates
- **.claude/agents/**: 4 new Python/FastAPI specialized agents
  - simplified_technical_lead.md: Architecture and technical guidance
  - fullstack_developer.md: FastAPI backend + Dash frontend implementation
  - simplified_qa.md: pytest testing and quality assurance
  - simplified_devops.md: Docker deployment and server infrastructure

## 🧪 Testing Infrastructure
- **pytest.ini**: Complete pytest configuration with coverage requirements
- **tests/conftest.py**: Comprehensive test fixtures and database setup
- **tests/unit/**: Example unit tests for auth and application services
- **tests/integration/**: API integration test examples
- Support for async testing, AI service mocking, and database testing

## 🧹 Cleanup
- Removed 9 duplicate/outdated documentation files
- Eliminated conflicting technology references (Node.js/TypeScript)
- Consolidated overlapping content into comprehensive guides
- Cleaned up project structure for professional development workflow

## 🚀 Production Ready Features
- Docker containerization for development and production
- Server deployment procedures for prototype hosting
- Security best practices with JWT authentication and RLS
- Performance optimization with database indexing and caching
- Comprehensive testing strategy with quality gates

This update establishes Job Forge as a professional Python/FastAPI web application
prototype ready for development and deployment.

+## Performance Guidelines for Job Forge
+
+### Backend Optimization
+- Use async/await for all database operations
+- Implement connection pooling for PostgreSQL
+- Cache AI-generated content to reduce API calls
+- Use database indexes for application queries
+- Implement pagination for application lists
+
+### Frontend Optimization
+- Use Dash component caching for expensive renders
+- Lazy load application data in tables

+### Code Quality
+```python
+# Example FastAPI endpoint structure
+from fastapi import APIRouter, Depends, HTTPException, status
+from sqlalchemy.ext.asyncio import AsyncSession
+from app.core.security import get_current_user
+from app.models.user import User
+from app.schemas.user import UserCreate, UserResponse

+
+router = APIRouter()
+
+@router.post("/users", response_model=UserResponse, status_code=status.HTTP_201_CREATED)
+async def create_new_user(
+    user_data: UserCreate,
+    db: AsyncSession = Depends(get_db)
+) -> UserResponse:
+    """Create a new user account with proper validation."""

+            status_code=status.HTTP_400_BAD_REQUEST,
+            detail="Email already registered"
+        )
+    
+    # 2. Create user with hashed password
+    try:
+        user = await create_user(db, user_data)
+        return UserResponse.from_orm(user)

+            detail="Failed to create user"
+        )
+```
+
+### Database Design - Job Forge Specific
+```sql
+-- Job Forge multi-tenant schema with RLS
+CREATE TABLE users (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    email VARCHAR(255) UNIQUE NOT NULL,
+    password_hash VARCHAR(255) NOT NULL,
+    first_name VARCHAR(100),
+    last_name VARCHAR(100),
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+
+CREATE TABLE applications (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    user_id UUID NOT NULL REFERENCES users(id) ON DELETE CASCADE,
+    company_name VARCHAR(255) NOT NULL,
+    role_title VARCHAR(255) NOT NULL,
+    status VARCHAR(50) DEFAULT 'draft',
+    job_description TEXT,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+
+-- Enable RLS for multi-tenancy
+ALTER TABLE applications ENABLE ROW LEVEL SECURITY;
+
+CREATE POLICY applications_user_isolation ON applications
+    FOR ALL TO authenticated
+    USING (user_id = current_setting('app.current_user_id')::UUID);
+
+-- Optimized indexes for Job Forge queries
+CREATE INDEX idx_applications_user_id ON applications(user_id);
+CREATE INDEX idx_applications_status ON applications(status);
+CREATE INDEX idx_applications_created_at ON applications(created_at DESC);
+```
+
+### AI Integration Patterns

+        prompt = f"""
+        Generate a professional cover letter for:
+        User: {user_profile['name']}
+        Experience: {user_profile['experience']}

+        """
+

+        except Exception as e:
+            # Fallback to OpenAI or template
+            return await self._fallback_generation(user_profile, job_description)
+```
+
+### Testing Requirements - Job Forge
