Goals

Build for V8 isolates first.
Make it isomorphic to work across all modern JS runtimes.
Use options injection for all keys and settings.
Support multiple CLERK_API_KEY for multiple instance REST access.
Align JWT key resolution algorithm across all environments (Function param > Environment variable > JWKS from API).
Tested automatically across different runtimes (Node, CF Workers, Vercel Edge middleware.)
Clean up Clerk interstitial logic.
Refactor the Rest Client API to return {data, errors} instead of throwing errors.
Export a generic verifyToken for Clerk JWTs verification.
Align AuthData interface for SSR.
Export CJS and ESM.

Remaining tasks

[] Build test coverage
[] Run suite in Deno runtime
[] Custom claim validation in verifyToken for JWT templates
[] Replace QUnit with Mocha in a browser-like setup using ESM.
[] Replace Sinon with https://mswjs.io
[] Add tribute to https://github.com/cfworker/cfworker/tree/main/packages/jwt
[] Make test suite files load dynamically so that we don't need to manually update suites.ts every time we add a new test file.
[] Dynamic resource parsing to remove the deserializer
