N6/C2: player-initiated duels — staked, no-death PvP

`!duel @user [stake]` (+ `!adventure duel`; accept/decline/status). A staked
arena bout resolved through the auto-resolve combat engine.

The engine is asymmetric — N player-seats vs one monster-shaped enemy, no seat
for a second PC — so a duel builds each fighter as their real player Combatant
and synthesises the opponent as an enemy stat block from their sheet. That is
lopsided (player side = full kit, enemy = flat stat block), so the bout runs
BOTH orientations and decides on aggregate remaining-HP fraction, cancelling the
attacker-seat edge. To-hit stays faithful both ways (d20 + AttackBonus vs AC);
damage folds into one enemy Attack (per-hit × swings + companion-proc
expectation); DamageReduct ports over. Casters fight weapon-only in both
orientations — accepted, PvP class balance is out of scope per the plan.

Economics: both escrow the stake on accept (pool 2×stake); winner 70%, community
pot rakes 30% (a sink); exact-HP-tie draw refunds both. Stake capped at
level×€500. W/L reuses adventure_rival_records; shared 7-day pair cooldown.

Terminal fate is serialised by an atomic claim (DELETE … WHERE id=? gated on
RowsAffected==1, mirroring communityPotDebit): accept/decline/the expiry ticker
all claim first, only the winner moves euros — no stake can be both resolved and
refunded across the 24h boundary. issueDuel runs under advUserLock; accept
re-checks the challenger and builds both fighters before debiting the challenged.
Rides the 1-min eventTicker; combat golden byte-identical; suite green.
