frank-primary: cutover state to Qwen3.8-Flash-Next Q8_0 (6 shards, PLE pinned, MTP4, sharp template)

- env: STATE_FILE -> r9v-state/q8xl; add dev-overlay adapter mount
  (quantized inject shard dequant, fork 363d606), FULL_MUTABLE_CACHE=0
  (80-slot tiered vs the overlay's uncensored 160-slot injection), and
  the qwen-sharp-v22.4.0.jinja chat template via the launcher's new
  R9V_CHAT_TEMPLATE_FILE/KWARGS passthrough (fork 30d4a32)
- serve/deploy: shard gates extended to SHARD4/5/6 (unset-safe, the
  uncensored rollback state carries none)
- seams: STATE_FILE/LLM_PRIMARY_STATE -> q8xl
