refactor(parse5-utils): migrate tests from mocha/chai to node:test
Replace mocha globals and chai assertions with node:test and node:assert/strict. Update test:node script to use `node --test`. - `expect(x).to.equal(y)` -> `assert.equal(x, y)` - `expect(x).to.eql(y)` -> `assert.deepEqual(x, y)` - `expect(x).to.exist` -> `assert.ok(x)` - Add `--test-force-exit` to prevent test hangs from open handles Assisted-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
