feat(sidecar): protocol 14 — the world event call forward (PLAN_REDESIGNS §14.3.1)

POST /world/call, a thin forward like /world/place: the body is stamped
`world.call` whatever it names, so the route cannot place, revert or zone
anything. What a call starts is kept, so nothing is remembered here; the
plugin keeps the call's key. The `world.event` frames (24 types, told apart by
`event`) ride the feed like any other event, and hello's `console` like any
other field. Still protocol 14 (D332); one new test, 71 pass.
