ChannelRhiView replaces the legacy QPainter raw-trace painter with a QRhiWidget that uploads channel data as vertex buffers and draws every visible trace in a single shader invocation. It manages its own pipeline, samplers, resource bindings and a small CrosshairOverlay for the time / amplitude cursor, and exposes callbacks for the host ChannelDataView to push new samples, change scaling or update the visible window.
