Commit Message

feat: add Transport abstraction for SSH connections

Introduce Transport interface so each provider controls how SSH
connections are established. DirectTransport for single-node and SSH
provider. SSMTransport for AWS cluster mode with retry-based dial (D1).
Provisioner unchanged — just receives working connections.

- Transport interface with Dial() and Target() methods
- DirectTransport: TCP dial to host:22 (existing behavior)
- SSMTransport: AWS SSM port forwarding with exponential backoff retry
- Provisioner gets functional option WithTransport()
- NodeInfo gets InstanceID and Transport fields
- Backwards compatible: nil transport falls back to DirectTransport
