frank-default-large: ngram-mod only — both MTP draft heads incompatible

Browse Source 
Both the EasiiX Q8_0 and agentionai ROCmFP4-FAST MTP draft heads fail
with 'missing tensor blk.0.hc_attn_norm.weight' against the STRIX_LEAN
Uncensored model. The qwen4exp binary expects this hyper-connection
attn norm tensor which neither draft GGUF carries. Using ngram-mod
only until a compatible MTP head is found.
