Ask Claude to write tests.

prompt: Please write tests for this library using vitest. The tests should use a mock or fake KV namespace for storage. Be sure to study README.md and storage-schema.md in addition to oauth-provider.ts to fully understand the functionality. Try to cover all the important logic.

Claude initially wrote a separate mock library.

prompt: Let's just put the whole test including mocks in one file.

Claude spent several minutes thinking and produced the test. It failed immediately due to `cloudflare:workers` not being available.

prompt: Looks like for this test to run under node, we need to mock out the `cloudflare:workers` module. We just need to define the `WorkerEntrypoint` class. Can you do that?

Claude did this. Yay.

Several tests are still failing, but they do run. Will debug in separate commits.
