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.

+## Hash Tracking
+
+Each config entry stores an upstream commit hash comment:
+  `# Upstream: club-3090 <hash> (<date>) - <compose-file>`
+
+When comparing, first extract stored hashes. If a config's hash matches
+upstream HEAD, skip it (report "already synced"). Only full-diff configs
+whose hash differs. Update the hash comment when edits are applied.

-2. Compare upstream compose files to the three local llama-swap entries. Translate docker-compose semantics into the existing `docker run`/llama-swap format.
