Pull request overview

Updates the hot-reload test setup to rely on Rspack’s built-in CSS handling instead of style-loader/css-loader, and adjusts the fixture HTML + snapshots accordingly.

Changes:

• Switch reload fixtures’ .css handling from loader-based to type: 'css'.
• Update the HTML generator used in tests to include emitted CSS assets via <link> tags.
• Remove loader dependencies and update hot-reload snapshots to match the new HMR output.
