Refactors SslKeyLogger to take the ClientHello random at flush() time
(removes the lookup-lambda + bindConnection ceremony) so the formatter
is testable without spinning up a real QuicConnection. Adds three
unit tests covering: the four NSS Key Log lines emitted in the right
order, flush idempotency, and lower-case hex encoding.
Also drops a checked-in implementations.json snippet
(quic-interop-runner-snippet.json) so a sibling clone of the runner
can be registered with one jq merge instead of hand-edited JSON.
