feat(sim): F4.2 the sim protocol, the simulation room and LocalSimHost; M9 measured

packages/protocol holds the one list of /sim messages and checks every field, naming what is wrong. packages/sim has the simulation room for F and the web worker: the document's snapshot at start, the engine's clock on the wall clock with Java's speed as cable delay, subscriptions to cable activity, a card's new frames and a program's new window lines, capture and clock kept over a stop, the command line as first action, a core failure told to every client. LocalSimHost mirrors the document into the worker and back without echo. M9 in Chromium: 17 examples give the same capture as in Node, character for character; the room runs in a real worker.
