feat(create-webpack-app): stop asking about HTML and CSS

[alexander-akait]

Summary

#4833 moved the init templates onto webpack's built-in HTML and CSS support, but the questions about them stayed. Since webpack handles both out of the box, init no longer asks whether to simplify HTML creation, which CSS solution to use, whether PostCSS is wanted, or whether CSS should be extracted: index.html is always the entry point and a stylesheet is always scaffolded. One question remains for the preprocessors webpack does not cover (SASS/LESS/Stylus), wired through a type: "css/auto" rule that adds only the preprocessor loader. The default template goes from 9 questions to 5. Refs #4833.

Generating and building each template also surfaced three defects that predate both PRs and are fixed here: baseUrl for the Vue TypeScript paths (TS5090), a fully specified ./router/index.js import under "type": "module", and Svelte 5's mount() instead of new App(), which rendered a blank page.

What kind of change does this PR introduce?

feat

Did you add tests for your changes?

Yes — test/create-webpack-app/init/init.test.js gains a case asserting the HTML/CSS questions are gone and that the generated config and dependencies carry no html-webpack-plugin/css-loader/mini-css-extract-plugin, plus a case covering the preprocessor path (type: "css/auto" with only sass-loader); the prompt sequences and snapshots are updated. Beyond the suite, each template was generated and production-built, and the emitted dist/index.html loaded in Chromium: every one renders with its stylesheet applied and no page errors, SASS/LESS variants included.

Does this PR introduce a breaking change?

No for generated projects. The prompts change, so the cssType, isCSS, isPostCSS and html answers are replaced by a single cssPreprocessor answer — this only affects anything driving the generator with pre-supplied answers.

If relevant, what needs to be documented once your changes are merged or what have you already documented?

Documented in this PR: packages/create-webpack-app/README.md notes that every template relies on webpack's built-in HTML and CSS support, and each template's generated README.md explains that the page is the entry point and how to add a preprocessor.

Use of AI

Yes. Claude Code made the template and generator edits and ran the verification described above — generating every template, building it, and loading the result in a browser. I reviewed the diff and the verification output before submitting.
