1st Timeline 1.6.0 — 端点分隔线
时间段端点分隔线
- 时间段的开始/结束日期渲染为时间轴上的主题色水平分隔线：文字居中，线条向两端延伸渐隐，悬浮时提亮染色，与上方进度条一一对应
- 同日包含排序：开始分隔线自动排在当日所有事件上方，结束分隔线排在下方
- 新增「时间段端点标记」设置开关；移除进度条显示开关（进度条改为常显）
Range endpoint dividers
- Range start/end dates now render as theme-colored horizontal divider lines on the timeline — centered text, lines fading out to both sides, brightening on hover — matching the progress bars above
- Same-day inclusion ordering: the start divider ranks above all events on its day, the end divider below
- New "Range start/end markers" setting toggle; the progress-bar visibility setting was removed (bars are always shown)
