Subject: [PATCH] Optimize array allocations and evaluation in
 CacheoutViewModel

Replaced eager `.filter` operations with `.lazy.filter` and `.contains(where:)` in computed properties `selectedSize` and `hasSelection`.

To avoid unnecessary intermediate array allocations on every UI update, minimizing memory churn and improving rendering performance. Short-circuits evaluation in `hasSelection` from O(n) filtering to O(1) in best case, and eliminates an O(n) intermediate array allocation in `selectedSize`.
