fix(routing): correct Route Callback connection offsets

The batch rule was added at index 4 but connections weren't updated,
causing all subsequent rules to route to wrong handlers:
- select → Answer List Callback (wrong)
- list → Answer Action Callback (wrong)
- action → Answer Noop Callback (wrong)
- noop → nothing (missing)

Fixed by correcting outputs 5-8 to connect to proper handlers.
