// Reads Configs/NpcActivityCatalog.json — the server copy of the client's
// AgentDataSetsActivityConfig (284 rows), generated by _gen_npc_life_cfg.py out of
// 补丁和工具\DUMPS\readable_world_dump_4229938_final.zip
// (01_CONFIGS/npc_systems/table/AgentDataSetsActivityConfig.json).
// Why it matters: this is the table that turns "an NPC tag" into "a place and a performance".
// AgentDataSetsActivityCfgId on the agent's sync info is an id into THIS table, and
// MapPosition is where the official build actually puts the character (Richie on the
// treadmill at 1191,0,2052 is just one row). 153 of the 284 rows carry a real position; all of
// them sit in the two open-world raids (23300888 / 23300999).
// The id also reaches the UI: NpcDaliyManager:OnRenderActivity resolves it through the same
// table for the icon/description, and MapSubSystem_SpiritAcquisition reads the schedule's
// RaidId + NpcScheduleInfo.Position to drop the map marker — which is why the login frame's
// FavorNpcDailyScheduleInfos should carry these coordinates too.
