Improve parameter descriptions in sequential-thinking for better LLM type safety

Update thoughtNumber and totalThoughts parameter descriptions to use positive-only examples that guide LLMs toward correct numeric type usage. This addresses the issue where LLMs sometimes generate string values (e.g. "1") instead of numeric values (e.g. 1) for integer parameters.
