      Add limit: 1 optimization to $filter for First() and FirstOrDefault() methods with predicates
       

      - Before: { $filter: { input: '$array', as: 'x', cond: { $gt: ['$$x', 1] } } }

- After: { $filter: { input: '$array', as: 'x', cond: { $gt: ['$$x', 1] }, limit: 1 } }

       

      With limit: 1, MongoDB stops filtering after finding the first matching element instead of scanning the entire array
