Description

Is your feature request related to a problem? Please describe.
Passkeys are meant to be used across devices. This takes the form of either syncing or using the phone as an
authenticator. This can happen for example via scanning a QR code

Describe the solution you'd like
Implementing CTAP2 hybrid transport and the correspondenting INTENT handler.

Additional context

I'm not even sure if it isn't implemented yet, at least the intent handler isn't. During a quick look through the source code I didn't find anything but I'm not equipped to touch security critical code

Research direction

No files, tests, or entry points are named. Start by searching the source for existing passkey, CTAP2, transport, and INTENT handling, then trace how authenticator requests are routed; the work is done when hybrid transport and its INTENT handler are implemented with appropriate security-focused coverage.
