v1.45.0

Added

• Slider ComposableScreen UIElement — a continuous numeric input bound to
  a variable. Value is stored as a stringified float (kind: "float") so
  expressions/conditions coerce it numerically. Props: variableName,
  defaultValue (number), min (0), max (1), step (0 = continuous), plus
  minimumTrackTintColor / maximumTrackTintColor / thumbTintColor and
  disabled. Schema refines min <= max. Exposed via SliderElementProps and
  the UIElement union / UIElementSchema.
