- 组件 Tag 数量预算不再写死在 ResolveTagBudget(...) 里，而是走 RarityTagBudget.txt -> DRRarityTagBudget -> RarityTagBudgetRuleRegistry -> InventoryTagRuleService 这条表驱动链。
- TagBudget.txt:1 新增了按品质的 MinCount/MaxCount，预算缓存和加载入口分别在 RarityTagBudgetRuleRegistry.cs:7 和 ProcedurePreload.cs:18。
- 生成逻辑已经接到新规则，InventoryTagRuleService.cs:10 现在会先按 Tag.txt 过滤/加权，再按 RarityTagBudget 决定抽几个 Tag。
