User: "When should I use Strategy vs. State?"

Process:
1. Comparison: Key differences and similarities
2. Strategy: Client chooses algorithm (independent)
3. State: State transitions automatically (related)
4. Examples: Domain-specific examples for each
用户: "我何时应该使用Strategy vs. State？"

流程:
1. 对比：关键差异与相似点
