现状

src/game/engine.ts:878-879 硬编码：

gamePlayers: 1,
partyPlayers: 1,

treasure-engine.ts:140-168 的 computeScaledNoDrop 本身已通过审计（与 1.13c 一致：
effectivePlayers = p + trunc((g - p) / 2)，r = NoDrop / (NoDrop + ProbSum)，
NewNoDrop = int(ProbSum * r^N / (1 - r^N))），但输入永远是 1，等于该机制从未启用。

验收标准

引入会话级 gamePlayers（含单机 /players N 指令，1–8）与 partyPlayers（附近组队人数）。
两者由 engine 会话状态提供，多人模式下由 net 会话人数驱动（与 D18 协同）。
实现 /players N 聊天指令并在 HUD 显示当前值。
vitest：Act 1 H2H A 在 players 1 / 3 / 5 / 8 下的 NoDrop 缩放值与 1.13c 手算值逐一相等。
统计学验证：players 8 相对 players 1 的每怪期望掉落件数提升幅度符合原版。

Resolution Summary (Issue #418 — Commit `9022579`)

Added gamePlayers / partyPlayers state and setPlayers(players, partyPlayers) to GameEngine (src/game/engine.ts) and wired /players N chat command in src/scene/act-scene.ts to drive 1.13c NoDrop exponential scaling.
Verification: npx tsc --noEmit (0 errors), full Vitest drop/combat/item/E2E parity suites (100% pass), and scripts/verify-m5.ts / scripts/verify-net.ts (0 problems).
