feat(llama-swap): add --default-chat-template-kwargs to vLLM 3090 configs

Sync all three Qwen3.6 27B vLLM configs (tools-text, long-text,
long-vision) with club-3090 83bf73d. Adds disable-thinking flag
and introduces upstream hash tracking comments for future syncs.

Update update-vllm-3090-configs skill to use hash-based skip logic.
