- Removes the `behavior`/`sidebarRevealBehavior` plumbing throughout
activation and reveal call sites now that every reveal jumps
immediately, eliminating the need to special-case newly created
worktrees.
- Reworks worktree-sidebar-reveal.ts to center the target row within
the viewport and temporarily pad list boundaries so first/last rows
can still center instead of clamping to the edge.
- Drops the reduced-motion e2e workaround since reveals no longer
animate.
