Subject: build: Configure Vite for library build and finalize package fields

- Add `vite-plugin-dts` dev dependency.
- Create `vite.config.ts` specifically for library build mode:
    - Configure ESM and UMD outputs (`dist/digiid-ts.es.js`, `dist/digiid-ts.umd.js`).
    - Set up `vite-plugin-dts` for generating `dist/index.d.ts`.
    - Externalize Node.js built-ins and 'digibyte-message' dependency.
- Update `package.json`:
    - Change `scripts.build` to `vite build`.
    - Point `main`, `module`, and `types` fields to the correct files in `dist/`.
- Run and verify the build process successfully generates the expected distribution files.
