Robert Wojciechowski 3058b11ff2 Remove list splitter/collector feature and refactor distributed modules
- Remove DistributedListSplitter and DistributedListCollector nodes
- Remove /distributed/init_list_queue and /distributed/request_list_item endpoints
- Clean up all references from prompt_transform, queue_orchestration, constants, and tests
- Refactor and reorganize distributed modules for quality improvements
