Refactored the sorting callback in DomainsTable.svelte to remove the allocation of temporary arrays and `Array.prototype` methods on every iteration. Used explicit primitives and math logic instead to remove GC pressure and improve sorting performance. Co-authored-by: yeboster <23556525+yeboster@users.noreply.github.com>

💡 What: Refactored the
handleSortmethod insideDomainsTable.svelteto remove temporary array destructuring ([aVal, bVal]) and array prototype operations (slice/reverse) within the sort callback, replacing it with direct primitive assignment and mathematical multipliers (1 or -1) for sorting direction.🎯 Why: When
Array.prototype.sort()is called, the callback executes on the order ofO(N log N)times. Using array object creation and native prototype methods inside this tight loop creates massive garbage collection overhead that blocks the main thread, especially on slower devices or larger tables.📊 Impact: Reduces GC pauses and increases the speed of frontend sorting for domains by completely eliminating object allocation during iterations.
🔬 Measurement: Inspect memory allocation timeline during multiple domain list sorts to confirm a reduction in temporary array instances and reduced main thread blocking time.
