isPortLinked

Whether the given port already appears as an endpoint of any link. A physical port models one cable termination, so it can host at most one link at a time. Callers use this to reject attempts to wire a second link onto an already-connected port — `linkExists` only catches exact-duplicate links, which isn't enough for the "1 port = 1 link" invariant.
