Replaced sequential `forEach` loop in `performAutoDeletion` with parallel execution using `supervisorScope`, `async`, and `awaitAll`. This reduces the execution time significantly when multiple chapters need to be deleted, as file I/O operations (cache clearing) now run concurrently. Benchmark results: - Baseline (Sequential): ~2000ms (1000ms delay + 10 * 100ms I/O) - Optimized (Parallel): ~1100ms (1000ms delay + ~100ms I/O) - Improvement: ~45% total reduction (~90% reduction in I/O phase) Co-authored-by: Aatricks <113598245+Aatricks@users.noreply.github.com>

💡 What: Optimized
ReaderViewModel.performAutoDeletionto delete chapter caches concurrently instead of sequentially.🎯 Why: To prevent blocking the coroutine for extended periods when multiple chapters are eligible for auto-deletion, improving overall responsiveness and background task efficiency.
