类型工厂：锁定全局路径与元数据类型，生成定制化的实例化函数。
Type Parameters
P
P extends MeshPath
当前项目定义的路径字面量类型 (MeshPath)
S
S extends any[] | Record<string, any> = any
初始 Schema 的结构定义
NM
NM extends Record<string, any> = any
节点元数据 (Node Metadata) 的类型定义
Returns

Description
这是一个高阶函数（Currying），旨在解决泛型冗余。通过预先注入 MeshPath (P) 和 MetaType (NM)， 你会得到一个“专属”的实例化工具，从而避免在业务代码中反复书写冗长的泛型尖括号。 工作流：
- 在项目初始化/配置文件中定义：
const defineMesh = useMeshFlowDefiner<MyPaths, MyMeta>(); - 在业务逻辑中实例化：
const engine = defineMesh('app-engine', schema, { ... });
