When using a transparent background color, fillRect composites rather than replaces pixels. Add clearRect before fillRect in renderLine, clear, and renderScrollbar to properly erase previous content before applying the background color. This fixes content piling up when using transparent backgrounds and ensures selection highlighting clears properly. Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

Problem
When setting the terminal background to a translucent or transparent background, the canvas writing approach ends up stacking up stale content. This PR fixes that.
My first draft actually looked at the background color to decide if it was opaque and then skipped the
clearRectfor that scenario, however I don't think there is a perf hit here so have gone for the more simple approach, if you'd prefer this other approach then please let me know 🙂Summary
