capsite/toybox: ingress is a capability; a hello-world web vat

Browse Source 
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.
