⚡ Bolt: Prevent intermediate array allocations with lazy filter

[acebytes]

💡 What: Replaced eager .filter operations with .lazy.filter in CacheoutViewModel and MenuBarView.
🎯 Why: In SwiftUI computed properties and view bodies, eager .filter creates intermediate arrays every time they are evaluated, leading to unnecessary memory churn and allocations.
📊 Impact: Eliminates O(N) intermediate array allocations when calculating selectedSize, categories count, and top categories.
🔬 Measurement: Check memory profile during UI updates and ensure tests pass.

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).
