fix(scripts): RoomSceneStart setPlayerData bindTo contract + runtime validation

Critical fix: - setPlayerData fake state lacked subscribe() -> PlayerInfoView.bindTo threw TypeError at runtime. Switched to PlayerInfoView.applyPlayer({nickname, bean,avatar}) when available; falls back to bindTo + proper reactive store with subscribe/value if only bindTo is exposed. Runtime validation (per CLAUDE.md 第二准则 — no silent fallback): - computePositions / setSeatLayout: validate layout ∈ VALID_LAYOUTS - computePositions / setPlayerCount: validate count ∈ [1,8] AND is integer - setPlayerData: validate seat is integer ∈ [1, currentCount] - extractPlayerViewData: validate nickname/bean/avatar types (no ?? 兜底) - start(): validate no null/undefined entries in playerSlots Architecture: - Extracted pure controller logic to room-scene-controller.ts so tests can import without cc mock (RoomSceneStart remains thin cc wrapper that delegates). Matches existing pattern of room-scene-layout.ts. Tests: - Added 27 new tests (validate* / apply* / extract* / clearSlots) - 5 original layout tests kept; 254/254 PASS (222 prior + 32 room-scene) Spec: - Resolved 2x2/triangle/square contradiction: Success Metrics + 成功标准 both defer coordinates to layout sub-task, consistent with 不覆盖 section.
