fix: infinite loop in result contexts

[vbreuss]

This PR fixes an infinite loop issue in the ResultContexts class by correcting the linked list insertion logic. When adding a new context to a non-empty list, the previous implementation incorrectly inserted the new node between the first node and its successor, creating a circular reference. The fix properly prepends the new context to the front of the list.

Key Changes

• Corrected the linked list insertion logic in ResultContexts.Add() method to prevent infinite loops
