What and why?
Adds CheckboxRecorder, a new ElementRecorder implementation that captures Flutter Checkbox widgets in Session Replay. Without this recorder, checkboxes were matched by CustomPaintRecorder and rendered as a SRPlaceholderWireframe, showing a generic box with an × inside regardless of their actual state. This ensures checked, unchecked, and tristate states are faithfully represented in replays.
How?
CheckboxRecorder resolves the widget's visual properties (fill color, checkmark color, border, visual density) by walking the widget properties and theme fallback chain, matching Flutter's own rendering logic. It produces a single SRTextWireframe per checkbox: the box shape is rendered via shapeStyle/border, and the checkmark symbol (✓, —, or empty) is centered as its text. The subtree is ignored to prevent CustomPaintRecorder from double-capturing the inner CustomPaint.
