Add a separate Vite library build (vite.lib.config.ts + `build:lib`) that
bundles src/index.ts to ESM with React/react-dom externalised and the 97
internal `@/` imports resolved at build time, plus type declarations and
copies of tokens.css / typography.css into dist. Point package.json
exports/main/types at dist and make react a peer dependency, so ADS can be
consumed as an installed package (@geljic/ads3-design-system) rather than a
file: + `@/` alias dependency.
