When the unique suspenders filter is off, non-suspended Suspense boundaries now appear gray (using --color-dim) instead of the environment color, making it easy to distinguish which boundaries actually caused loading states. This applies to both the scrubber pills and the layout rects. The hasUniqueSuspenders field is passed through SuspenseTimelineStep so the scrubber can use it directly without an extra store lookup.

Why?
When displaying all Suspense boundaries (filter off), every boundary is colored blue, making it hard to distinguish suspended from non-suspended or Parent suspended from the same ones. This change makes it easier to identify those Suspense boundaries so you can remove or lower them to keep the necessary Suspense closer to the dynamic data source.
