refactor(canvas): 节点注册表 - 收敛素材类型、生成模式与输入计数判据

把三条按类型分支的语义判据收进注册表：
- resourceKind  原 canvas-resource-references.ts，作为 @ 引用素材时的类型
- generationMode 原 canvas-connection-policy.ts，作为生成节点时的模式
- inputKind     原 canvas-connection-policy.ts，被容量校验计数时的类别

resourceKind 与 inputKind 刻意分成两个字段：它们语义不同——空图片节点不是素材
（不进 @ 引用），但照样计入 imageCount。合成一个会静默改掉连线容量校验。

两处必须保住的语义，均已由测试钉住：
1. 角色卡（workflowKind === character）是跨类型覆盖，对任何节点类型生效，
   属于查注册表之前的前置判定，因此留在调用点而不进 per-type 定义。
2. 排除必须早于覆盖。原实现先 return 掉生成配置与背板，之后才判角色卡；
   若把角色卡判定提前，带角色元数据的配置/背板节点会被多算成 characterCount。

新增 test/canvas-node-registry.test.ts（19 用例 / 77 断言）并加入 package.json
的 test 列表——该列表是显式枚举，不加进去文件不会跑。补测的原因是
canvas-resource-references.test.ts 只覆盖 collectUpstreamVideoNodes，
本次改动的 resourceKind 此前零覆盖，而这类判据出错不报错、只会让 @ 引用少收素材。

顺带内联 nodeGenerationMode（迁移后退化为单行转发）。
