docs(runicnpc): stage 4 decisions D249-D251

D249: RunicNPC gets API 3 in stage 4 (a fifth PR): a call that creates and
names a placement from a map point it grounds and checks, rename and respawn
calls, and a hook raised when a placement changes.
D250: per-profile kills on the player's public stats, as a title category,
and as a leaderboard ranked by a picked profile.
D251: where an adopted server profile and a site profile share a name on
that server, the site's wins; the server's own is kept as "replaced".
