v0.3.0

Added

• Per-model pricing: session rows and daily/monthly stats bill each session at the price table of the model it actually used (v4-flash / v4-pro), so sessions that switched models stay accurate
• auto price mode: flat legacy rates until 2026-08-17 00:00 Beijing time, then automatically switches to DeepSeek's official peak/off-peak schedule; the footer badge shows flat / peak / off-peak rate accordingly — no config change needed

Changed

• Footer redesigned into three columns: status + price mode | current cost | date + time
• Stats view simplified: dropped "Summary"/"Trend" headings, cumulative total label enlarged into one line
• Curve Y axis reworked: unit label always visible, compact ticks (1B/500M), floating value pill at the latest point
• Stats and live views aligned to identical heights; footer cost unified with stats figures

Fixed

• Invisible budget bar (0.2.2 regression): replaced nonexistent theme tokens with the real suffixed variables
• Stats view crash (0.2.2 regression): React Hooks order violation
• Overestimated session cost: sessions mixing models were billed entirely at the current model's rate
• Double-container whitespace and grey scrollbar strip in the stats view

新增

• 按模型分别计价：会话行、按日/按月统计按各会话实际使用的模型（v4-flash / v4-pro 等）套用对应价格表，切换过模型的会话不再整段按单一模型计价
• auto 价格模式：2026-08-17 零时（北京时间）前自动使用 flat 旧价，之后自动切换 DeepSeek 官方峰谷价（高峰 9-12 / 14-18），底部徽章同步显示「标准价 / 高峰价 / 空闲价」，无需手动改配置

变更

• 底部栏改为三列布局：状态 + 价格模式 ｜ 当前花费 ｜ 年月日 + 时间
• 统计视图排版精简：删除「汇总」「趋势」标题，累计消耗标签加大单行显示
• 曲线 Y 轴重排：单位标签常驻、紧凑刻度（1B/500M）、当前值胶囊浮动在最新点旁，大数值不再重叠
• 统计与实时视图高度精确对齐；底部当前花费与统计口径统一

修复

• 预算进度条不可见（0.2.2 引入的缺陷）：主题 token 名称错误，已替换为主题真实定义的带后缀变量
• 统计视图崩溃（0.2.2 引入的缺陷）：React Hooks 顺序违规导致切换统计视图时面板消失
• 会话成本高估：会话混用模型时整段按当前模型计价的问题
• 统计视图双层容器造成的多余空白与灰色滚动条条带
