Dots3 NOTE has not adopted the DeepSeek V3.2 sequence-parallel execution path. Explicitly opt it out so inherited forwards do not access missing state or use incompatible sharding. Signed-off-by: KurodaKanbei <mistergalahad@gmail.com>

Why
The DeepSeek V3.2 sequence-parallel refactor changed the inherited forward paths to use
use_sequence_parallel.Dots3 NOTE uses custom model and decoder initializers and has not adopted the new sequence-parallel execution path. This causes serving to fail during KV cache profiling with:
AttributeError: 'Dots3NoteModel' object has no attribute 'use_sequence_parallel'What changed
Explicitly disable sequence parallelism for Dots3 NOTE and keep its existing non-SP execution path.
