fix(query): iterate over captures for the shortest size, not longest

[amaanq]

Closes #308

Problem

The condition for iterating in satisfies_eq_capture was wrong, it should not iterate for whichever amount between the length of the first node array and the length of the second node array is larger. It should take the shortest length, since both must be valid.

Solution

In the condition, set l to the shortest number between size1 and size2. This mimics the Rust code here
