console.log('\n🎯 Alternative Approaches Summary:');
console.log('✅ execSync: Works for quick commands, good error handling, timeout support');
console.log('✅ execAsync: Works for longer commands, non-blocking, good for async operations');
console.log('✅ Both support working directory and environment variables');
console.log('✅ Both have proper timeout and error handling');
console.log('✅ Much simpler than complex session/event systems');
console.log('\n💡 Recommendations:');
console.log('1. Use execSync for commands that complete in < 30 seconds');
console.log('2. Use execAsync for longer-running commands');
console.log('3. Use spawn for commands that need real-time output streaming');
console.log('4. Avoid complex session management for simple command execution');
console.log('5. Handle SSH separately using native ssh command');
console.log('\n🚀 Next Steps:');
console.log('1. Replace handleExecuteCommand with direct execAsync implementation');
console.log('2. Add SSH support using native ssh command');
console.log('3. Remove dependency on complex ConsoleManager for simple commands');
console.log('4. Keep session management only for interactive/persistent sessions');
console.log('\n✨ Test completed successfully! All alternatives are working.');
