ext/node: assert.deepStrictEqual(-0, 0) should throw

[77it]

Version: Deno 2.1.9 (stable, release, x86_64-pc-windows-msvc)
Version: Node v23.5.0

The following code can be run in both Deno and Node: in Deno -0 and 0 are deepStrictEqual, in Node are not. In both environments -0 and 0 are notStrictEqual.

import { test } from 'node:test';
import assert from 'node:assert';

test('negative zero test', () => {
	// Deno & Node: strict equal: NOT equal
	assert.notStrictEqual(-0, 0);

	// Deno: deepStrictEqual: equal
	// Node: deepStrictEqual: NOT equal
	if (typeof Deno !== 'undefined') {
		assert.deepStrictEqual(-0, 0);
	} else {
		assert.notDeepStrictEqual(-0, 0);
	}
});

Looks like we're not comparing these with Object.is() somewhere. That would return false for Object.is(-0, 0).
