Add a new pooled QuadList<T> (NET8+), and update QuaternaryList to use it instead of List<T>. - Added src/ReactiveList/Quaternary/QuadList.cs: a high-performance, ArrayPool-backed list with Add/Remove/AddRange/AsSpan/Enumerator and Dispose semantics. - Replaced List<T> shards with QuadList<T> in QuaternaryList and adapted usages (AsSpan(), AddRange calls, CopyTo, enumeration) to reduce allocations and improve bulk operations. - Fixed shard index calculation to use bitmasking: ((hash & 0x7FFFFFFF) & (ShardCount - 1)). - Added an _hasIndices fast-path to avoid unnecessary index notifications when no secondary indices exist. - Removed CollectionsMarshal usage and added CP.Reactive.Quaternary import. - Updated README.md benchmarks and memory comparison to reflect QuaternaryList/QuadList performance and memory improvements. These changes aim to reduce allocations and improve throughput for large/bulk operations while preserving existing API behavior.
