Chains `.lazy` before `.filter` calls in SwiftUI computed properties (`MenuBarView` and `CleanConfirmation`) that precede `.count` and `.sorted()`. This prevents the allocation of intermediate arrays, reducing memory churn during view re-renders. Co-authored-by: acebytes <2820910+acebytes@users.noreply.github.com>

💡 What: Chained
.lazybefore.filteroperations that precede.countand.sorted()in computed view properties.🎯 Why: Eager
.filteroperations create temporary intermediate arrays, causing unnecessary memory churn and allocations when views re-render during state changes.📊 Impact: Eliminates O(N) array allocations per UI update for
MenuBarViewandCleanConfirmationSheet, reducing garbage collection overhead and memory spikes.🔬 Measurement: Profile with Xcode Instruments (Allocations template) and observe zero intermediate
