Subject: [PATCH] Optimize `selectedSize` computation in CacheoutViewModel

Update the `selectedSize` computed property in `CacheoutViewModel` to use `scanResults.lazy.filter(\.isSelected).reduce(0) { ... }` instead of using `selectedResults.reduce`. This prevents the creation of a redundant intermediate array of `ScanResult` items every time the property is accessed, which happens frequently during UI renders. This reduces memory churn and improves overall UI performance by switching from an O(n) array allocation to a lazy O(1) space accumulation.
