⚡ Bolt: [performance improvement] Optimize CacheoutViewModel computed properties

[acebytes]

💡 What: Replaced eager array filtering with .lazy.filter for size reduction, and .contains(where:) for boolean checks in CacheoutViewModel.
🎯 Why: Computed properties relying on selectedResults were previously generating intermediate array allocations on every view update. hasSelection evaluated the entire filtered collection just to check if it was empty.
📊 Impact: Eliminates unnecessary array allocations and short-circuits execution for hasSelection, saving CPU cycles and memory churn during UI refreshes.
🔬 Measurement: Verify memory allocations profile when toggling cache item selection in the UI.

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).
