* fix(stores): Actually check a vector is a unit vector/normalized
Instead of just summing the components to see if they equal 1.0, take
the actual magnitude/p-norm of the vector and check that is
approximately 1.0.
Note that this shouldn't change the order of results except in edge
cases if I am too lax with the precision of the equality
comparison. However it should improve performance for normalized
vectors which were being misclassified.

* fix(stores): Add tests for known results and triangle inequality
This adds some more tests to check the cosine similarity function has
some expected mathematical properties.
