Fill in the HuggingFace source repo for five weight variants that had no direct
download recipe (were "manual"), each verified live against the HF API:
- gemma-4-31b:bf16 → google/gemma-4-31B-it
- qwen3.6-27b:awq → cyankiwi/Qwen3.6-27B-AWQ-INT4
- qwen3.6-35b-a3b:gptq_int4 → palmfuture/Qwen3.6-35B-A3B-GPTQ-Int4
- qwen3.6-35b-a3b:dflash → z-lab/Qwen3.6-35B-A3B-DFlash
- qwen3.6-35b-a3b:dflash_gguf → abhinand/Qwen3.6-35B-A3B-DFlash-GGUF
These are now fetchable via `WEIGHT_KEY=<model>:<variant> bash scripts/setup.sh
<model>` (and, once a compose adopts them, one-click in the c3 Download UX).
Weights-registry tests green.
