Clean Code Review

基于《代码整洁之道》原则，聚焦 7 个高收益检查维度。

Review Workflow

Review Progress:
- [ ] 1. Scan codebase: identify files to review
- [ ] 2. Check each dimension (naming, functions, DRY, YAGNI, magic numbers, clarity, conventions)
- [ ] 3. Rate severity (高/中/低) for each issue
- [ ] 4. Generate report sorted by severity

核心原则：功能保留

所有建议仅针对实现方式优化——绝不建议改变代码的功能、输出或行为。
