食物增强(foodstats)

## v3.0.4 - Bug Fix

### 🔧 Fixed
- Fixed negative saturation progress when switching bonus modes
  - After switching from "Per Unique Food" or "Per N Unique Foods" mode
    to "Saturation Threshold" mode, bonuses triggered in other modes
    are no longer incorrectly counted as saturation consumption
  - Each mode now tracks its progress independently

### 📝 Technical
- Added a dedicated saturation-mode trigger counter (saturationBuffCount),
  separated from the total buff count (buffCount), to avoid cross-mode data pollution

## v3.0.4 - Bug 修复

### 🔧 修复
- 修复切换增益模式后饱食度进度显示为负数的问题
  - 从「每种新食物」或「每N种新食物」模式切换到「饱食度累计」模式后，
    之前在其他模式下触发的加成次数不再被错误计入饱食度消耗
  - 现在各模式的进度独立计算，互不干扰

### 📝 技术说明
- 新增独立的饱食度模式触发计数器（saturationBuffCount），
  与总加成次数（buffCount）分离，避免跨模式数据污染
