issue: #44358 The panic "concurrent map iteration and map write" was introduced in PR #44361. It occurred when QueryCopySegment RPC iterated segmentResults while copySingleSegment was updating it concurrently. - Deep copy segmentResults in Clone() to avoid shared map reference - Return map copy in GetSegmentResults() to prevent iteration conflict - Update tests to get task from manager after Update() operations This fix follows the same deep-copy pattern used in ImportTask and L0ImportTask.
