feat(core): modems run — the pair in the project, and a modem of another project hands its frames on (K0–K2)

Measured first: tools/java-oracle's ModemRun joins two networks by a pair of Java modems over TCP on localhost. The modem has no card and adds no delay of its own — a frame takes the cables on both sides, nothing more. The core pairs the two enabled modems on a port (Swift's inProject, with its conditions and cycle suppression) on Java's timing: no 20 ms. The modem example of FILIUS now pings through instead of failing the core. A modem of another project (relay) gives its frames to whoever runs the engine and puts on its cable what comes back, with this engine's frame and packet numbers; a frame dies after MAXIMUM_RELAY_HOPS trips.
