O(n²) complexity: the nested items × tags loop will slow down on large lists. Build a Map<id, name> for tags and perform O(1) lookups instead.

The nested loop drops items without matching tags. The previous implementation kept those items with an undefined tagName, so this refactor can remove rows unexpectedly.

refreshCache introduces a side effect into a data-building function. Move it out so buildList remains pure and easy to test.

tagName can be undefined when an item has no matching tag, causing a.tagName.length to throw during sorting. Provide a safe default or filter unmatched items explicitly.
