test(S-cfc-96): diet.food.healthAdjust 契约级单测（RED，预期红）

健康问卷四维（饮食习惯/过敏/用药/主要健康体症）调整食材推荐的契约级单测，
溯源 2026-11-09-diet-recommendation-health-questionnaire-adjust.md §1-3（A1-A5）。

- A1: HealthFilterService 应提供 checkFoodBlocks / checkDietPreferenceAdjust，
  loadProfile 并入 lifestyle.allergySymptoms（反射+Mockito 行为探测）
- A2: FoodRecommendService.getCurrentFoods 每食材输出 adjustment/adjustmentReason
- A3: Food 增加 @TableField(exist=false) 瞬态字段 adjustment/adjustmentReason
- A5: generateIngredientList 补充 checkDrugInteractions 用药维度 + dietType 宗教饮食过滤
- A4: reportId 分支快照不变（说明性用例）

验证（RED）：mvn -Dtest=DietFoodHealthAdjustContractTest test
Tests run: 10, Failures: 9, Errors: 0（9 条契约断言失败即 RED 达成）

+/**
+ * 契约级单测：能力键 {@code diet.food.healthAdjust}（健康问卷四维 → 食材推荐个性化调整）。
+ *
+ * <p>契约来源（2026-11-09-diet-recommendation-health-questionnaire-adjust.md）：
+ * <blockquote>
+ *   用户 2026-11-09 拍板：报告解析出的食材推荐，须按健康问卷「饮食习惯 / 过敏 / 用药 / 主要健康体症」
+ *   做个性化调整（§1-2）。设计落点 §3 A1-A5：HealthFilterService 按食材检查扩展 + FoodRecommendService
+ *   getCurrentFoods 接入 + Food 瞬态字段 + generateIngredientList 口径补齐。
+ * </blockquote></p>
+ *
+ * <p>调整分级（叠加在现有 score「适合/戒备」之上的第二层个性化）：
+ * <ul>
+ *   <li>{@code adjustment=blocked}：健康问卷硬性不建议（D1 过敏 / D2-risk1 药物禁忌 / D3 疾病 / D4 绝对避免 / D5 宗教 / D8 年龄），前端红条 + 「适合」Tab 降底；</li>
+ *   <li>{@code adjustment=warning}：软警告/间隔提示（D2-risk2/3），前端黄条，位置不变；</li>
+ *   <li>{@code adjustment=boost}：明确偏好（D6 must_eat），前端绿条置顶；</li>
+ *   <li>{@code adjustment=normal}：无调整。</li>
+ * </ul>
+ * 判定顺序：blocked（D1/D2-risk1/D3/D4/D5/D8）→ warning（D2-risk2/3）→ boost（D6）→ normal。</p>
+ *
+ * <p><b>实现现状（src/main 核实）</b>：本分支 src/main 中 {@code HealthFilterService.checkFoodBlocks /
+ * checkDietPreferenceAdjust} 方法、{@code Food.adjustment / adjustmentReason} 瞬态字段、
+ * {@code loadProfile} 的 lifestyle.allergySymptoms 合并均未落地；{@code FoodRecommendService.getCurrentFoods}
+ * 输出 Map 无 adjustment/adjustmentReason；{@code BeijingNutritionService.generateIngredientList}
+ * 未调用 checkDrugInteractions、未按 dietType 做宗教饮食过滤。因此本测试以「反射结构契约 + Mockito
+ * 行为契约 + 源码锚点」探测实现缺失：能编译通过、能运行、断言失败（红），且失败断言原文清晰可贴。</p>
+ *
+ * <p><b>GREEN 升级指引</b>：实现者按 §3 A1-A5 落地后，本测试自动转绿：A1 提供 checkFoodBlocks /
+ * checkDietPreferenceAdjust（适配 Food 命中面）并让 loadProfile 并入 allergySymptoms；A2 在
+ * getCurrentFoods 每食材 Map 追加 adjustment/adjustmentReason；A3 给 Food 增加
+ * {@code @TableField(exist = false)} 瞬态字段并透传；A5 在 generateIngredientList 循环内补
+ * checkDrugInteractions 与宗教饮食过滤。</p>
+ *
+ * <p><b>测试范围</b>：仅用 JUnit5 + Mockito（无 Spring / 无 DB / 无外部服务），与同批 RED 契约测试
+ * （TeamProfitHookContractTest / FamilyJoinValidationRulesContractTest）同风格。</p>
