Richard Loyer 0407ac8b71 dist: ROOT CAUSE crash dense-HTP = matmul HMX (fp16) ; fix = HVX pour le dense 
Analyse complète (méthode SSM_CONV) du crash dense-HTP:
- bench HTP synthétique (pp512, +tg8) = OK ; cli/engine texte réel crashe 0x2e > ~14 tokens.
- OPFILTER bisect: SOFT_MAX/ROPE/RMS_NORM/GET_ROWS/CPY/CONT/ADD n'arrêtent PAS le crash ; MUL_MAT->CPU OUI.
- GGML_HEXAGON_USE_HMX=0 (matmul HVX) supprime le crash, =1 le reproduit. => le matmul HMX (fp16 tile)
  faute sur les activations réelles du dense (massive activations Qwen3 > plage fp16 ; bench synthétique
  ne déclenche pas l'overflow). Analogue du SSM_CONV pour la 3.5, mais ici c'est le matmul HMX coeur.

Câblage: lecture general.architecture dans le GGUF AVANT init backend -> hybride (qwen35/qwen3next):
HMX on + option C (préservé) ; dense: USE_HMX=0 + HTP contexte-unique (HVX, ~40 prefill =3x CPU, decode ~11,
stable). Repli CPU si pas de HTP. Validé test_jni_native: dense (HVX HTP) + 3.5 (option C) cohérents.
TODO backend: matmul HMX robuste aux activations hors plage fp16.
