  • 💡 What: Replaced eager array filtering with .lazy.filter and .contains(where:) in frequently evaluated SwiftUI computed properties.
  • 🎯 Why: SwiftUI evaluates computed properties on every state change and render pass. Eagerly filtering arrays (filter) causes continuous intermediate array allocations leading to memory churn.
  • 📊 Impact: Eliminates O(N) array allocations during property access. Reduces UI stuttering by improving memory efficiency.
  • 🔬 Measurement: Observe Memory graph in Xcode during selection toggles to confirm the absence of transient Array allocations.

Replaced eager array filtering with `.lazy.filter` and `.contains(where:)` in frequently evaluated SwiftUI computed properties.

SwiftUI evaluates computed properties on every state change and render pass. Eagerly filtering arrays (`filter`) causes continuous intermediate array allocations leading to memory churn. Eliminates O(N) array allocations during property access. Reduces UI stuttering by improving memory efficiency.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

Closing as duplicate. The Bolt bot has opened many PRs for the same lazy-filter / short-circuit / array-allocation optimizations in CacheoutViewModel.swift and MenuBarView.swift / CleanConfirmation.swift. Consolidating on #393 as the canonical (most recent iteration).
