feat(char-rp-reasoning): Deckard-PKD (Qwen3.5) replaces RpR-v4 after autonomous A/B

Operator wanted a reasoning-RP model that tolerates DRY (RpR-v4 forbids rep/DRY -> a
1/30 loop tail). Ran the full A/B on brokkr's 30-prompt D1 suite (content-only, slop-scored):

- Deckard-PKD (Qwen3.5-27B, DavidAU creative tune) WON: 0/30 loops, 0/30 refusals, clean
  managed reasoning (native Qwen3.5 <think>/enable_thinking), DRY-tolerant, ~57 tok/s,
  runs on the base llama-swap b8840 image. -> now the char-rp-reasoning seat (:8018).
- RpR-v4: 0 refusals but 1/30 loop (no-DRY). Pantheon-27B: clean slop but 7/30 explicit
  refusals + needs the newer ggml-org/llama.cpp image (Qwen3.6 won't load on b8840).
  Snowdrop + Gembrain (Gemma-4): floored (llama.cpp can't manage their reasoning without
  the vetoed template hacks). Losers kept on disk as alternates.
- char-rp (Magidonia) unchanged; gen unchanged. gateway char-rp-reasoning -> Deckard
  sampler (temp 1.0/top_p 0.95/top_k 40/min_p 0.05; DRY server-side).
