refactor: replace goto with structured control flow

Browse source 
- spell_handler.cpp: replace goto-done with do/while(false) for pet
  spell packet parsing — bail on truncated data while always firing
  events afterward
- water_renderer.cpp: replace goto-found_neighbor with immediately
  invoked lambda to break out of nested neighbor search loops
