/// <summary>
/// 任务运行时模型 (TaskModel)
/// 设计说明：
/// 1) TaskDefinition 描述“配置”，TaskModel 描述“运行时进度”。二者分离利于 Mod 追加内容。
/// 2) 任务状态只保存必要字段，展示文本统一由 Definition + i18n 输出。
/// 3) 任务参与单位只记录 Id，避免模型直接引用 Node。
/// 注意事项：
/// - 如果没有 DefinitionId，可使用 Name 作为临时演示数据。
/// - Deadline 语义是“剩余回合数”，由 TurnSystem 递减。
/// 未来扩展：
/// - 可加入阶段状态（灵感/写作/实验/审核），与 UI 进度条分段对应。
/// - 可加入失败原因/完成评级，用于结算与肉鸽评分。
