Description

In @std/assert equal():

1. Boxed primitive objects (new Number(1), new Boolean(true), Object(1n), Object(sym)) have no own enumerable keys and were treated as empty objects matching each other regardless of their underlying primitive values. This adds checks comparing their .valueOf() using sameValueZero.
2. When comparing Set and Map collections with object elements/keys, the non-primitive loop simply decremented a counter whenever an entry in a matched any entry in b, without tracking whether that entry in b was already matched. As a result, duplicate entries could match the same target entry multiple times (e.g. Set([{a: 1}, {a: 1}]) vs Set([{a: 1}, {a: 2}])). This tracks unmatched entries of b using a Set and deletes entries upon matching.
