A handler is a live reference, held by the VatAdmin DO; workerd evicts
an idle DO within seconds, and with it the handler, so a vat's page went
503 almost at once.
createVat now keeps a vat's params when they hold only data and
ingresses (an ingress by its key: the VatAdmin can make it again), and
which vat was given which ingress. A request for a mount with no handler
restarts that vat with its params; it rebuilds its root, serves again,
and the request is answered. A vat whose params hold another peer's
objects isn't restartable yet.
The test crashes its own toybox (a crash ends every session to it), and
the creator waits for the root's handoff before it disconnects, as
scripts/hello.js now does too.

E(vatAdmin).makeIngress(labels) reserves a mount and returns an ingress;
whoever holds it serves requests carrying those labels by calling
E(ingress).serve(handler). A vat gets one in its params, like any other
remote object; nothing in a vat's module is an entrypoint. A request
reaches the handler as passable data (method, path, labels, body), and
the response comes back as data (status, headers, body). The handler is
a live reference for now: after a restart its mount answers 503.
vats/hello.js serves hello, world; pnpm hello creates it on a running
toybox (client.js is the Node OCapN client, shared with the tests).
pnpm start and pnpm switchboard never ran: systemd-socket-activate wants
absolute paths for unix sockets.
