Validation script for all cross-platform fixes.

This script runs a comprehensive series of tests to validate that all applied fixes
work correctly on Windows, including:

1. Home directory pattern detection (Windows, macOS, Linux)
2. Unix path validation on Windows
3. Safe files functionality with temporary files
4. Cross-platform file discovery with Path.parts
5. Communication simulator logger and Python path fixes
6. BaseSimulatorTest logger and Python path fixes
7. Shell scripts Windows virtual environment support

Tests cover all modified files:
- utils/file_utils.py
- tests/test_file_protection.py
- tests/test_utils.py
- communication_simulator_test.py
- simulator_tests/base_test.py
- run_integration_tests.sh
- code_quality_checks.sh
