feat(09-01): add batch command detection and parsing

- Add "Detect Batch Command" code node to parse multi-container commands
- Add "Is Batch Command" IF node to route batch vs single container
- Add "Route Single Action" switch to route single commands to appropriate flow
- Add "Get Containers for Batch" node for Docker API container list
- Modify Keyword Router to route restart/start/stop/update through batch detection
- Single container commands route to existing Parse Action/Update Command flows
- Batch commands (2+ containers) route to new batch processing flow

Batch detection logic:
- Pattern: {action} {name1} {name2} ... where action is update/start/stop/restart
- Single container = not batch (existing flow)
- Two or more containers = batch (new flow)
