Add async-safe polyfills, Jest custom config, and improved token validation

- Introduced Web Crypto API polyfills (`@peculiar/webcrypto`) for Node.js to enable SSR-safe cryptography utilities. - Added Jest setup file for global mocks (e.g., `localStorage`, `sessionStorage`, and `TextEncoder/Decoder`). - Enhanced token validation behavior in `storage` tests to reject incomplete tokens. - Replaced runtime configuration validation with clamping using `parseIntSafe` constraints for improved reliability. - Updated `package.json` and `package-lock.json` to include new dependencies (`@peculiar/webcrypto` and related libraries).
