Release v1.4.21 with download engine performance optimizations

- Cache itemCount as class property instead of O(n) Object.keys().length on every emit/persist/UI update
- Eliminate redundant iteration: hasQueuedItems now delegates to findNextQueuedItem
- Remove expensive cloneSession from getSnapshot (IPC serialization handles the copy)
- Increase speed events compaction threshold (50 → 200) to reduce array reallocations
- Time-based UI emit throttling instead of per-percent progress checks
- Avoid Array.from allocation in global stall watchdog
- Optimize markQueuedAsReconnectWait to iterate only run items instead of all items
- Cache pathKey computation in claimTargetPath loop (avoid path.resolve per iteration)
- Use packageOrder.length instead of Object.keys(packages).length in getStats
