Adds the v0.7.3 critical-path plumbing for both MoE models:
* Compose files:
- models/gemma-4-26b-a4b/vllm/compose/single/docker-compose.yml
(vllm-nightly-clean, TP=1, port 8040, bf16 KV, no drafter)
- models/qwen3.6-35b-a3b/vllm/compose/single/preview.yml
(vllm-nightly-clean, TP=1, port 8050, fp8_e5m2 KV, preview-only)
* COMPOSE_REGISTRY entries 'vllm/gemma-a4b' and 'vllm/qwen-a3b-preview'.
* DrafterProfile: new gemma-26b-it-assistant for the 26B-A4B
(google/gemma-4-26B-A4B-it-assistant — separate weights from 31B);
qwen-mtp-builtin.model_compat extended with qwen3.6-35b-a3b.
* vllm-nightly-clean.supported_model_families adds qwen3-next-moe as a
preview/smoke route; notes clarify Cliff 2 / TQ3 unavailable here.
* Qwen 3.6 35B-A3B model: requires_genesis flipped false → upstream is
strictly bootable on post-#42521 nightlies; Genesis is RECOMMENDED for
production (TQ3 KV + Cliff 2 mitigations), not strictly required to boot.
* ModelProfile gains kv_calc_supported (defaults true). Both new MoE
models set false because tools/kv-calc.py only models qwen3.6-27b and
gemma-4-31b today (MoE + asymmetric KV + DeltaNet+attention hybrid all
require new MODEL_SPECS + activation coefficients — queued for Codex).
fits() now skips C12 for kv_calc_supported=false instead of failing.
All compat tests pass; both new composes fit on 1x-3090 (Gemma) and
1x-3090/2x-3090/1x-5090 (Qwen preview).
