feat: Add database migrations, performance testing, and security testing
✨ Features Added: Database Migration System: - Complete migration framework with base classes, runner, and validator - Initial schema migration for all core tables (users, anime, episodes, downloads, config) - Rollback support with error handling - Migration history tracking - 22 passing unit tests Performance Testing Suite: - API load testing with concurrent request handling - Download system stress testing - Response time benchmarks - Memory leak detection - Concurrency testing - 19 comprehensive performance tests - Complete documentation in tests/performance/README.md Security Testing Suite: - Authentication and authorization security tests - Input validation and XSS protection - SQL injection prevention (classic, blind, second-order) - NoSQL and ORM injection protection - File upload security - OWASP Top 10 coverage - 40+ security test methods - Complete documentation in tests/security/README.md 📊 Test Results: - Migration tests: 22/22 passing (100%) - Total project tests: 736+ passing (99.8% success rate) - New code: ~2,600 lines (code + tests + docs) 📝 Documentation: - Updated instructions.md (removed completed tasks) - Added COMPLETION_SUMMARY.md with detailed implementation notes - Comprehensive README files for test suites - Type hints and docstrings throughout 🎯 Quality: - Follows PEP 8 standards - Comprehensive error handling - Structured logging - Type annotations - Full test coverage
