Pull Request Overview

This PR changes the default HTML plugin implementation from JavaScript-based ('js') to Rust-based native implementation ('native'). The native implementation produces HTML link tags with a different attribute ordering, placing the href attribute before the rel attribute. All test expectations have been updated to match this new attribute order.

Key Changes

• Changed default html.implementation from 'js' to 'native' in the core configuration
• Updated all HTML link tag assertions in e2e tests to expect the new attribute order (href before rel)

Changing the default from 'js' to 'native' is a significant breaking change that affects HTML output format. The documentation at line 1605 in types/config.ts states '@default 'js'' which should be updated to reflect this new default value of 'native'.
