Unified Test Runner for Trading System

This script provides a unified interface to run all tests in the system:
- Essential functionality tests
- Model persistence tests  
- Training integration tests
- Indicators and signals tests
- Remaining individual test files

Usage:
    python run_tests.py                    # Run all tests
    python run_tests.py essential          # Run essential tests only
    python run_tests.py persistence        # Run model persistence tests only
    python run_tests.py training           # Run training integration tests only
    python run_tests.py indicators         # Run indicators and signals tests only
    python run_tests.py individual         # Run individual test files only
