Session log: qwen3.6 benchmark, route strict-format to 3.6

Benchmarked qwen3.6 (36B MoE) vs qwen3:14b and qwen3:32b on 16
representative prompts. qwen3.6 scored 15/16 vs 14b 11/16 and 32b
12/16, winning every strict-format/adherence test (multi-step rules,
weekend-aware scheduling, prompt-injection resistance, word-limit
summary). Single reasoning regression noted for re-check at qwen3.7.

Updated .claude/OLLAMA.md (Models, Documentation Engine, and
When-to-Use tables) and .claude/CLAUDE.md one-line model summary to
route strict-format work to qwen3.6 and keep bulk prose on qwen3:14b
(2x faster). Also removed openclaw npm package + ~/.openclaw data dir
earlier in the session.

+Routing basis: 16-prompt benchmark on 2026-05-16 (`benchmark_qwen_3_6.py` in repo root). qwen3.6 scored 15/16 vs qwen3:14b 11/16 and qwen3:32b 12/16. 3.6 won every strict-format and adherence test (multi-step rules, schedule reasoning with weekend trap, prompt-injection resistance, word-limit summary) — at the cost of ~2x slower inference. **Known regression**: 3.6 missed one small reasoning prompt (3 vs expected 4) that 14b/32b got — re-validate when qwen3.7 lands. qwen3:32b is dominated on every axis; not in routing rotation.
