fix(package): 🐛 Harden npm package configuration

[haskou]

Changes

• Add stricter npm package metadata: exports, engines, sideEffects, and runtime tslib.
• Require coverage thresholds and remove the test mode that allowed no tests.
• Generate UUID and ShortId values internally using existing secure random bytes, removing external ID generator dependencies.
• Modernize lint/Jest/TypeScript config for the latest toolchain.
• Update and prune dependencies so the package stays lighter.

Why

The published package referenced tslib from dist without declaring it as a runtime dependency, which breaks clean consumers. The package also carried avoidable runtime/dev dependencies and older tooling config.

Validation

• yarn lint
• yarn build
• yarn test:coverage with 100% global coverage
• npm pack + install in a clean temporary consumer + require package + generate UUID, ShortId, and SymmetricKey
• yarn outdated returns no outdated packages
