l3ocho b646e2f5df 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- Removed 9 duplicate/outdated documentation files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.
