Tracks upstream chenbstack/glint v0.1.27-beta.2: two-finger touch scrolling and stale-connection recovery in Web Remote (chenbstack#97), and the white-flash fix when closing a split (chenbstack#99). Both cherry-picked cleanly onto the distribution branch.

Summary
Root cause
When a split collapsed, the incoming host could claim the surviving surface before it entered the window. A final update from the outgoing tree then treated that detached incoming host as abandoned and stole the surface back, leaving the survivor blank until a later SwiftUI update restored it.
Performance
The normal path adds only generation and attachment-state comparisons. The race path schedules one main-queue callback; there is no polling, timer, or continuous redraw.
