Subject: [PATCH] frank-large: pin Qwen3.8-Flash-Next sampler settings +
 preserve_thinking

halogen-flash-server has no server-side sampler defaults (temperature absent
or 0 = greedy), so the endpoint decoded greedy for OMP, whose global
sampling settings default to -1 (not sent).

compat.extraBody merges these top-level into every request body after the
compat policy, so they win:
  temperature=1.0 top_p=0.95 top_k=20 min_p=0.0
  presence_penalty=0.0 repetition_penalty=1.0 preserve_thinking=true

Verified against the live dankclaw endpoint: preserve_thinking is honoured
(350 vs 75 prompt tokens for a replayed reasoning turn), and the exact
body shape returns 200.
