feat(char-rp-gguf): replace broken Angel NVFP4 with dual GGUF RP seat on ana-ml2 GPU0

char-rp        -> TheDrummer Magidonia-24B-v4.3 Q6_K (Magistral prose, ~65 tok/s,
                  zero refusal, tight POV) via llama.cpp (:8016).
char-rp-reasoning -> ArliAI QwQ-32B-RpR-v4 Q5_K_M (abliterated managed reasoning,
                  ~52 tok/s, reasoning surfaces in reasoning_content) via llama.cpp (:8018).

- New canonical stack stacks/char-rp-gguf/ (llama-server x2, GPU0-pinned, ~86/97G
  co-resident with gen). GGUF sidesteps the vLLM-NVFP4 + Mistral-tokenizer traps that
  killed the Angel serve. Never Ollama.
- Best-of-breed per seat: no single dense 24-32B is both an elite non-thinking prose
  seat AND a clean managed-reasoning seat on llama.cpp (Magidonia [THINK] boundary is
  loose; Cydonia-R1 <think> runs away; QwQ is template-managed). Pantheon-Reasoning-27B
  stays rejected (re-censors in <think>; RpR-v4 abliterated reasoning is the fix).
- Gateway rewired: char-rp->:8016, char-rp-reasoning->:8018, Mistral/QwQ samplers,
  dropped the Qwen enable_thinking kwarg. One-model Magidonia fallback documented.
- Retired the ms32-24b-angel stack.
