feat: add css module support and refactor utils

This commit introduces support for CSS modules in the Svelte
preprocessor. It also includes a significant refactor of the utils
module. The alias loading function has been moved to its own file
(alias.ts) and the CSS module related functions have been moved to
css-module.ts. The old utils.ts file has been removed. The package.json
and pnpm-lock.yaml files have been updated to include new dependencies
required for the CSS module support.
