Passkeys can be stored just like password hashes!

I'm proposing an interoperable $webauthn$v=1$… format, and a Go API that uses these passkey records for authentication.

I'm looking for feedback before proposing this as crypto/passkey for Go 1.28!

@filippo I wonder if it's Ok to ask a basic question, what do passkeys provide in which passwords don't? In principle, it looks like passwords are passwd[:32] and passkeys are passwd[32:]?
