CSimulation2 used , CSimulation2Impl mixed /, and CTurnManager used for the same turn-count concept, forcing a static_cast<int64_t> at the one place these types already met (rejoin-test comparison). Add (alias for std::int32_t) in SimulationCommand.h and use it consistently for every turn counter in CSimulation2/Impl, CTurnManager and its subclasses (CLocalTurnManager, CReplayTurnManager), CNetServerTurnManager/CNetClientTurnManager, and the network wire format (m_Turn in CEndCommandBatchMessage, CSimulationMessage, CSyncCheckMessage, CSyncErrorMessage, and m_CurrentTurn in CLoadedGameMessage). Turn *duration* fields (m_TurnLength, m_CommandDelay, DEFAULT_TURN_LENGTH, COMMAND_DELAY_SP/MP, SetTurnLength, GetSavedTurnLength return type) are left as u32 — they're milliseconds, not a counter, and out of scope here. Remaining turn_id_t vs size_t comparisons use std::cmp_equal or explicit casts, matching the existing pattern in Simulation2.cpp. Fixes #8718
