重构: base 包资源核心类型迁移到 req/resx,新增 res_watcher/res_api_param

base/resource.go、resource_hooks.go、resource_test.go、query_field.go 删除,ResField 等具体实现搬到 req/resx(见 res_field.go 里的类型别名)。res_listener.go 替换成 res_watcher.go,对应资源变更监听概念改名。新增 res_api_param.go 及配套测试(ResApi 参数建模,给 MCP tool 的 JSON Schema 生成用)。

base/user.go
