feat: 航线 Y 偏移 1/2 幅宽、推荐帧率/曝光时间计算、速度默认值调整

- 第一条航线 Y 坐标偏移 1/2 幅宽，不再紧贴绘制区域边缘
- 生成航线时自动计算推荐帧率和曝光时间（Pika L 900像元 / Pika NIR 320像元）
- 推荐帧率×曝光时间=999，Pika L 最大帧率限制 250fps
- 生成航线后自动填入子任务帧率和曝光时间
- Y 轴定位速度默认 10cm/s，X 扫描 3cm/s，X 回起点 10cm/s

+
+每次 `git commit` 时需要同时更新版本号和 update.md：
+
+1. **更新版本号**：Cargo.toml、tauri.conf.json、package.json 中 PATCH+1
+2. **更新 update.md**：在文件头部插入新版本条目
+3. **变更内容由模型根据实际改动总结**，需注明需求来源（如某人提出）
+
+### update.md 格式
+```
+## vX.Y.Z (YYYY-MM-DD)

 # Spectral Insight Mission Plan - 更新日志
 
+## v0.0.10 (2026-06-25)
+
+- 第一条航线 Y 坐标偏移 1/2 幅宽，不再紧贴绘制区域边缘
+- 生成航线时自动计算推荐帧率和曝光时间（Pika L 900像元 / Pika NIR 320 像元，帧率×曝光时间=999）
+- 生成航线后自动填入子任务帧率和曝光时间
+- Pika L 最大帧率限制 250fps（唐超）
+- Y 轴定位速度默认值修改为 10cm/s，X 扫描速度 3cm/s，X 回起点速度 10cm/s
+
+## v0.0.9 (2026-06-25)
+
+- 航线生成画布支持 scanConfig 坐标范围（修改 X/Y 范围后画布随之更新）
+- 修复 Y 轴标签位数超过 3 位时溢出画布边框的问题
+- 画布按扫描区域宽高比等比例显示（x:y 不再强制 1:1）
+- 相机参数（FOV / 高度）改为纵向排列，右侧参数面板更窄
+- 画布占比提升至 85%
+
+## v0.0.8 (2026-06-22)
+
+- 子任务按设备类型显示不同背景色和左侧色条（Pika L 绿 / Pika NIR 蓝 / 单反 橙 / 深度相机 红）
+- 修复折叠时子任务标题高度不一致的问题
+
 ## v0.0.7 (2026-06-18)
 
 - fix: correct update.md v0.0.6 entry with proper 唐超 credit
