feat(rust): event NPCs named on the map, and a Place NPCs step's progress line (runicnpc stage 8)

- rust.npc.place's progress() (MODULE_API 1.12.0, D304). It reports the
  step's NPCs still standing, by its key, of how many it placed, with
  the profile's label: "Bandit: 2 of 3 left". A boss step is its
  health, "Walk Juggernaut: 59%", and a boss's adds are not counted.
  The data comes from the map's live answer, so it costs the game no
  extra ask. A reader who may not see the map's events layer gets no
  line.
- The map (D302, D303):
  - an NPC's tooltip is its name and its event's title, read from
    core's public calendar, which lists only announced events;
  - a boss is bigger and in its own colour, and an add says so;
  - a boss outside any event is in the world layer;
  - a boss's health is removed from what a viewer is sent.
- The world layer's visibility hint mentions those bosses.

coreApi stays ^1.11.0: an older core ignores the optional member, and
the action works without a progress line.
