Description

Set up test infrastructure so that subsequent tasks can write tests as they implement. Add test helpers for creating in-memory transport streams (mock transport), and skeleton integration test files for each component.

The mock transport is critical — it lets us test SSH client/server flows without actual network I/O, per ADR-001's consequence that "mock transports can produce in-memory streams."

Acceptance Criteria

• crates/wraith-core/tests/ directory with empty integration test skeletons: transport_tests.rs, client_tests.rs, server_tests.rs, auth_tests.rs
• crates/wraith-core/src/testutil.rs module (behind #[cfg(test)] or a testutil feature) exporting MockTransport and MockStream
• MockStream wraps tokio::io::DuplexStream implementing AsyncRead + AsyncWrite + Unpin + Send
• MockTransport implements Transport trait (once defined) returning MockStream via connect()
• MockTransportAcceptor implements TransportAcceptor (once defined) returning paired MockStream via accept()
• cargo test succeeds (even if no real tests yet)
