Move CSS processing from `load` to `transform` hook so framework
plugins (e.g. Vue SFC) can load virtual modules first. This prevents
ENOENT errors when the CSS plugin tried to read virtual paths like
`MyButton.vue?vue&type=style&index=0&lang.css` from disk.

…ut (#808)

* feat(css): add `css.inject` option to preserve CSS imports in JS output

When enabled, JS output retains `import './style.css'` statements pointing
to emitted CSS files so consumers automatically load the CSS.

- Add `css.inject` option to `CssOptions` (requires `@tsdown/css`)
- Support deprecated `injectStyle` top-level option for tsup migration
- Refactor `createCssPostHooks` into standalone `CssPostPlugin`
- Return `Plugin[]` from both `CssPlugin` functions
- Fix CSS asset hash resolution for async/split chunks
- Add migration transform: `injectStyle: true` → `css: { inject: true }`

* fix(css): preserve JS sourcemap when injecting CSS imports

Prepend a `;` to sourcemap mappings for each injected CSS import line,
keeping the JS sourcemap accurate after code modification.

* fix(css): rewrite pure CSS chunk imports in-place for correct order and sourcemap

Instead of removing pure CSS chunk imports and prepending CSS imports
(which reverses order and breaks sourcemap), swap the file extension
in-place (.mjs/.cjs/.js → .css). This preserves both CSS cascade
order and sourcemap line positions.

* fix(css): handle empty CSS wrapper chunks and dynamic entry injection

- Add relaxed detection in removePureCssChunks for wrapper chunks (JS
  files that only import CSS) while preserving entry/dynamic entry chunks
- Exclude isEntry and isDynamicEntry from pureCssChunks in inject plugin
  so dynamic entries get CSS imports prepended correctly
- Add test for shared CSS-only chunk import rewriting

* [autofix.ci] apply automated fixes

* refactor
