⚡ Bolt: Optimize UI computed property collection processing

[acebytes]

💡 What: Replaced eager array filtering and evaluation in CacheoutViewModel properties (selectedSize, hasSelection) with .lazy.filter and .contains(where:).
🎯 Why: The previous implementation created intermediate arrays and required O(N) evaluation for every UI cycle change, causing redundant memory churn.
📊 Impact: Eliminates redundant array allocations and short-circuits collection existence checks, reducing memory overhead and re-render work.
🔬 Measurement: Monitor UI responsiveness in the System Monitor when many cache categories or node_modules are selected and manipulated.

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).
