news: Pete learns to report a contract killing

gogobee's Mischief Makers ships four new event types — a hit going out, the
target walking away from it, the target not walking away, and the monster
turning up to an empty dungeon. Pete 400s an unknown event_type, gogobee retries
and then parks the bulletin forever, so this deploys first.

The anonymity is the story, not an implementation detail. A contract is
anonymous unless the buyer paid extra to sign it, so the lede reports the money
and pointedly not the name Pete doesn't have. A survival unseals the buyer
whether or not they signed — that exposure is the only brake on casual griefing,
and it's the one beat worth leading with. Being maimed buys you nothing: an
anonymous buyer stays anonymous when the contract lands.
