Include the final value in the sum.

Line 11 stops before the final element. Average([]int{2, 4}) returns 1 because it divides 2 by 2. Iterate through all values before division.

Proposed fix 
-	for i := 0; i < len(values)-1; i++ {
+	for i := 0; i < len(values); i++ {

In `@internal/reviewfixture/summary.go` at line 11, Update the loop in Average to
iterate through every element of values, including the final value, before
dividing the accumulated sum by the collection length.

The loop condition i < len(values) - 1 incorrectly excludes the last element of the slice from the sum, leading to an inaccurate average. It should be i < len(values) to include all elements.

The loop condition i < len(values)-1 is incorrect. It iterates from 0 up to len(values)-2, effectively ignoring the last element of the values slice. To calculate the correct average, the loop should include all elements. A correct implementation would be for i := 0; i < len(values); i++ or, more idiomatically in Go, for _, value := range values.

total += values[i]
}
return total / len(values)
}
