⚡ Bolt: [performance improvement] Short-circuit evaluation and prevent intermediate array allocations

[acebytes]

💡 What: Replaced eager .isEmpty checks on filtered collections with early-exiting .contains(where:) in hasSelection, and chained .lazy.filter before .reduce in selectedSize.

🎯 Why: SwiftUI computed properties are evaluated very frequently during render cycles. Unnecessary intermediate array allocations (from eager filters) and full traversals (from reducing over size > 0) create avoidable memory and CPU overhead.

📊 Impact: Eliminates O(N) array memory allocations for selectedSize and hasSelection, and turns hasSelection from a full O(N) collection iteration into an O(1) best-case / early-exit operation.

🔬 Measurement: Run Time Profiler/Allocations instruments during UI updates (checking and unchecking checkboxes); view fewer [ScanResult] heap allocations and faster hasSelection getter resolution.

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).

Understood. Acknowledging that this work is now obsolete (duplicate) and stopping work on this task.
