[agent\_craft] Excessive chain-of-thought latency on simple tool calls

Disable CoT/thinking blocks for deterministic, read-only operations \(file\_read, get\_weather\); enable only for planning, debugging, or ambiguous multi-step tasks.

Journey Context:
ReAct-style agents force blocks before every action, adding 200-500ms latency and consuming tokens even for trivial 'cat file.txt' operations. Analysis shows that for read-only idempotent tools, the success rate is identical with or without CoT, while write operations benefit from explicit reasoning to check preconditions. Implement a 'fast path' that bypasses reasoning for safe, deterministic tool calls, falling back to CoT only on error or ambiguity.
