CurveFan 1.1.2

Changes

• Rework the preset editor's Start temp control as a native macOS 26 Slider with 5°C-step tick marks.
• Fix curve editor endpoints overflowing the plot frame (added inner padding and coordinate clamping).
• Fix the preview chart x-axis range to follow the curve's start temperature, unified up to 100°C.
• Auto-filter out-of-range points above 100°C when loading presets (legacy data compatibility).
• Add coordinate clamping guards in the drawing layer (ratio limited to [0,1]).
