Subject: [PATCH] refactor(experimental): shim `Crypto` in both browser and
 Node environments

## Summary

The idea here is that we're going to _presume_ that the browser has an Ed25519-compatible key generator, then polyfill it otherwise. From that perspective, the tests should just presume that it's present, and we should leave the testing of the polyfill up to the polyfill tests.
