scoring: CORRECTION -- the death cost was never missing; my arithmetic was

Retracts the "open item" claimed in 2fcce53.  An ungated [deathcost] receipt
at the block settles it:

  [deathcost] player 2:1 advDmg=1 role=bound penalty=500 scoreBefore=-779
              -> APPLYING

It fires once, on a self-kill, exactly as it does on a combat death.  There is
no combat-vs-self asymmetry.

WHY I GOT IT WRONG: the cost is dispatched by a DIRECT
Player::ScoreMessageHandler() base call, so it never reaches the BT matchlog.
I computed the total from the LAST matchlog row and found no -500 in it -- but
that row is emitted BEFORE the unlogged cost.  I had noted the bypass one
message earlier and still failed to apply it to my own sum.  The lesson is the
usual one: a value that cannot appear in the log you are reading is not
evidence of absence.

The receipt stays.  A debit that moves the player-visible score while being
structurally invisible to the forensic log is exactly the kind of thing that
should announce itself.

Chart status after this: -500 special-case death cost VERIFIED applying.  The
-1000 eject ROW remains unverified -- its components (self-damage credit,
negated self-kill award, death cost) are each verified, but no real punch-out
has ever fired in a bench, so the total is still arithmetic.
