Fix export

[markwu35]

Need to export needed functions for the playground

---

Note

Low Risk
Low risk: changes are limited to package metadata/export map updates and package-lock.json flag adjustments, with no runtime logic changes. Main risk is accidental misrouting of consumers if any new subpath export paths don’t match built dist outputs.

Overview
Exports fix for consumers/playground. Updates package.json to add explicit subpath exports for client helpers (authorization, hash, permit2), server helpers (replay), and server/verifiers/*, plus constants, each pointing at corresponding dist JS and type definitions.

Also updates package-lock.json to mark several dependencies as peer: true (metadata-only lockfile change).
