/**
* @brief Factory for creating ModuleSystem implementations
*
* ModuleSystemFactory provides centralized creation of different execution strategies:
* - "sequential" -> SequentialModuleSystem (debug/test, one-at-a-time execution)
* - "threaded" -> ThreadedModuleSystem (each module in own thread)
* - "thread_pool" -> ThreadPoolModuleSystem (tasks distributed across pool)
* - "cluster" -> ClusterModuleSystem (distributed across machines)
*
* Each ModuleSystem type provides different performance characteristics while
* maintaining the same interface, enabling progressive scaling.
*
* Usage:
* ```cpp
* auto moduleSystem = ModuleSystemFactory::create("sequential");
* auto moduleSystem = ModuleSystemFactory::create(ModuleSystemType::THREAD_POOL);
* auto moduleSystem = ModuleSystemFactory::createFromConfig(config);
* ```
