Merge origin/main: sync Qwen3-8B no_think variant to Ansible repo (t_36e8ba68)

Resolved conflicts between local bafd76a (t_c5cef2b2, Qwen3-8B single-variant)
and origin/main 5cf4468 (t_664289a0, Qwen3-8B dual-thinking deployment).

Conflict resolution strategy: took origin/main version throughout — it is the
authoritative result from t_664289a0 which deployed the live no_think config to
astro-orbiter and already reflects the correct production state.

Changes incorporated from origin/main:
- defaults/main.yml: Qwen3-8B-Q4_K_M-no_think model entry (port 8107, n_gpu_layers=99,
  chat_template_file), row6 matrix entry, dual-thinking comment block.
- templates/llama-server-router-preset.ini.j2: [Qwen3-8B-Q4_K_M] with sleep-idle-seconds=60
  plus new [Qwen3-8B-Q4_K_M-no_think] section with chat-template-file directive.
- templates/qwen3-no-think.jinja.j2: new file — Qwen3 template with enable_thinking=false.
- tasks/models.yml: template deploy task for qwen3-no-think.jinja (chat_templates tag).
- tasks/swapmode.yml: GATE 2 assert updated to 7 models.
- templates/llama-swap-config.yaml.j2: chat_template_file flag support.

Also pulled in monitoring defaults (llm_monitoring_enabled, VRAM exporter settings,
Grafana dashboard vars, Prometheus scrape config) from origin/main monitoring branch.

; --- Aux model: Qwen3-8B-Q4_K_M -----------------------------------------------
; Added t_c5cef2b2 (2026-08-19, War Machine).
; Qwen3-8B is a dense 8B model (Qwen3 family, Alibaba) for aux tasks:
; intent classification, query rewriting, structured extraction, tool-call
; construction, and draft generation. Chosen over Llama-3.1-8B for superior
; json_schema grammar support and stronger instruction-following.
;
; Architecture: 36 layers, 32 Q heads, 8 KV heads (GQA), 32K native context,
; 131K via YaRN. Q4_K_M GGUF from bartowski/Qwen_Qwen3-8B-GGUF. ~4.68GB weights.
;
; ctx-size=32768: native training context (safe, no YaRN extension needed).
; VRAM at 32K ctx with q4_0 KV: ~4.68GB weights + ~0.5GB KV ≈ 5.2GB total.
; Fits comfortably on RTX 3090 24GB. Co-resident with nomic-embed (~84MB):
; ~5.3GB total — well within 24GB budget even as a warm auxiliary model.
;
; THINKING MODE NOTE (JARVIS clarification, t_c5cef2b2):
; Qwen3-8B has thinking (chain-of-thought) mode ENABLED BY DEFAULT.
; For latency-sensitive aux tasks (routing, rewriting, structured extraction),
; disable at call time — NOT in this deployment config:
; - Prompt prefix: begin the user message with "/no_think"
; - Chat template override: pass enable_thinking=False in the template vars
; (llama.cpp Jinja2 template: {% if enable_thinking is false %} ... )
; Do NOT hardcode thinking=false here — this is a call-site concern.
; Thinking mode IS appropriate for complex multi-step tool plans and long-context
; summarization; leave that decision to the caller.
;
; Source: bartowski/Qwen_Qwen3-8B-GGUF (public, no auth). Stored locally as
; Qwen3-8B-Q4_K_M.gguf (canonical name, trimmed from HF's Qwen_Qwen3-8B prefix).
; n-gpu-layers=99: GPU (all layers). At ~5GB, fully GPU-resident with headroom.
; flash-attn=true: Qwen3-8B uses standard attention; flash-attn is safe.
; sleep-idle-seconds=60: evict after 60s idle to free GPU VRAM for Qwen3.8-27B.
; --- Auxiliary model: Qwen3-8B-Q4_K_M (thinking variant) ----------------------
; GGUF: bartowski/Qwen_Qwen3-8B-GGUF (5,027,784,224 bytes)
; Thinking mode: ON BY DEFAULT (Qwen3 baked-in template, no override).
; - Use for complex aux tasks: long-context summarization, multi-step tool
; planning, structured extraction requiring CoT.
; - To suppress thinking at request time, send /no_think prefix in the prompt
; OR route to [Qwen3-8B-Q4_K_M-no_think] section below.
; n-gpu-layers=99: GPU-resident (~5.2GB VRAM). Cannot co-reside with
; Qwen3.8-27B-Q4_K_M (17.8GB). LRU eviction handles swapping.
; ctx-size=32768: 32K context, q4_0 KV cache.
; flash-attn=true: required for Qwen3 architecture at this context size.
; sleep-idle-seconds=60: evict after 60s idle (free VRAM for primary model).
; Added: t_c5cef2b2 (2026-08-19, War Machine) — initial Qwen3-8B deployment.

; --- Auxiliary model: Qwen3-8B-Q4_K_M (no-think variant) ----------------------

; for latency-sensitive aux tasks (intent classification, query rewriting,
; structured extraction, tool-call construction, draft generation).
;
; Both sections point to the same .gguf file — llama-server spawns independent
; child processes. VRAM cost: ~5.2GB per instance (~10.4GB total). Fits on
; RTX 3090 24GB alongside nomic-embed (84MB).
;
; Thinking variant (Qwen3-8B-Q4_K_M) remains available for complex tasks that
; benefit from CoT (long-context summarization, multi-step tool planning).
;
; Cannot co-reside with Qwen3.8-27B-Q4_K_M (17.8GB); LRU eviction applies.

FILE: roles/llm-inference-multimodel/templates/qwen3-no-think.jinja.j2
DESCRIPTION: Qwen3 chat template with enable_thinking unconditionally false.
This is a chat-template FILE deployed to {{ llm_models_dir }}/templates/qwen3-no-think.jinja
on astro-orbiter and referenced via chat-template-file in the INI preset for
[Qwen3-8B-Q4_K_M-no_think]. The [Qwen3-8B-Q4_K_M] section uses the model's
baked-in default template (thinking ON by default).
Mechanism: at the add_generation_prompt step, instead of checking
"enable_thinking is defined and enable_thinking is false"
we UNCONDITIONALLY emit the empty <think></think> prefix that suppresses CoT.
This is the hard-switch documented in the Qwen3 template spec and confirmed in
https://huggingface.co/blog/qwen-3-chat-template-deep-dive (section 1).
All other logic is identical to /opt/llama.cpp/models/templates/Qwen-Qwen3-0.6B.jinja
(the shipped template for Qwen3). Only the final add_generation_prompt block differs.
Added: t_664289a0 (2026-08-19, War Machine) — dual thinking deployment.
