Function installCryptoFallback

installCryptoFallback(scope?: CryptoScope): CryptoFallbackReport
Fill in the Web Crypto pieces a browser withholds outside a secure context, so the shell works when served over plain HTTP from an onion or overlay network address. crypto.getRandomValues is always present; randomUUID and subtle are not. Existing implementations are never replaced.

Call it once, before anything that may use Web Crypto.
Parameters
- scope: CryptoScope = globalThis
  The global to patch. Defaults to globalThis.
Returns CryptoFallbackReport
What was added.
Example
```
import { installCryptoFallback } from '@kernlize/core/crypto';
installCryptoFallback(); // { randomUUID: false, subtle: false } over HTTPS
```
