  • 💡 What: Switched from eager .filter to .lazy.filter before .count and .sorted operations.
  • 🎯 Why: Eager .filter forces the Swift runtime to allocate and populate an entire intermediate array before passing it to .count or .sorted.
  • 📊 Impact: Eliminates unnecessary array allocations and reduces memory churn.
  • 🔬 Measurement: Observe lower memory usage and fewer allocations when profiling with Instruments.

Switched from eager `.filter` to `.lazy.filter` before `.count` and `.sorted` operations. Eager `.filter` forces the Swift runtime to allocate and populate an entire intermediate array before passing it to `.count` or `.sorted`. Eliminating this unnecessary array allocation reduces memory churn.

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).
