* ⬆️ Update opencode and copilot deps * 🐛 Decouple workspace-content from workspace-local to reduce scroll re-renders Move workspace-local subscription from workspace-content* (parent) into viewport* and viewport-classic* (children). workspace-content* now only subscribes to the new workspace-vport derived atom, which changes only on window resize — not on every scroll event. This prevents the sidebar, palette and other workspace-content children from re-rendering on scroll. * 🐛 Throttle wheel events to one state update per animation frame Accumulate wheel event deltas in a mutable ref and flush them via requestAnimationFrame, so that multiple wheel events between frames produce a single state mutation instead of one per event. This prevents the cascade of synchronous React re-renders (via useSyncExternalStore) that can exceed the maximum update depth on rapid scrolling. Both panning (scroll) and zoom (ctrl/mod+wheel) are throttled. Scroll deltas are summed additively; zoom scales are compounded multiplicatively with the latest cursor point used as the zoom center. * ♻️ Extract schedule-zoom! and schedule-scroll! from on-mouse-wheel * ♻️ Avoid zoom dep on on-mouse-wheel by using a ref
