Code Review

This pull request introduces the ParallelHook class for concurrent hook execution, including documentation, type definitions, and tests. A potential race condition was identified in the handler method where modifications to the hooks array during execution could cause incorrect result mapping; snapshotting the array before execution is recommended.
