nsa_indexer.py imports log_cp_draft_shared_kv_debug from
cp_shared_kv_runtime, but ad358d164 defined it in nsa/utils.py.
The missing symbol caused deepseek_v2.py import to fail silently
(registry.py catches and warns), falling back to transformers.py
which loads unsharded 256-expert MoE parameters → OOM on H200.
