refactor(oocana)!: clean up FlowConfig and BlockConfig public API

[leavesster]

Summary

• Remove deprecated inputValues and toNode parameters from FlowConfig (use nodesInputs and nodes instead)
• Remove unused address parameter from FlowConfig
• Move searchPaths from FlowConfig and BlockConfig into RunConfig, unify type to string[]
• Rename buildArgs to buildRunConfigArgs for clarity

BREAKING CHANGE

• FlowConfig.inputValues removed — use nodesInputs
• FlowConfig.toNode removed — use nodes
• FlowConfig.address removed (was unused; broker address comes from connect())
• FlowConfig.searchPaths type changed from string to string[], moved to RunConfig
• BlockConfig.searchPaths moved to RunConfig

Test plan

• pnpm -F @oomol/oocana build passes
• pnpm -F @oomol/oocana test — 12 tests pass

Walkthrough

将运行时路径配置统一为 RunConfig.searchPaths，移除 BlockConfig/FlowConfig 中冗余与已弃用字段，重命名并调整参数构建函数为 buildRunConfigArgs，并同步更新示例与测试以传递 searchPaths: string[] 与新增 TypeScript 检查配置。

Changes

Cohort / File(s)	Summary
核心重构：运行配置与参数构建 packages/oocana/src/oocana.ts	新增 RunConfig.searchPaths?: string[]；从 BlockConfig 与 FlowConfig 中移除 searchPaths、address、toNode 与已弃用的 inputValues 样式字段；将 buildArgs 重命名为并替换为 buildRunConfigArgs（签名含 searchPaths）；更新 runBlock/runFlow 的解构与调用以使用新的构建函数，删除局部 searchPaths 处理。
示例与测试：传入参数形状调整 flow-examples/test/flow.test.ts, flow-examples/test/run.ts	调用 cli.runFlow 时将 searchPaths 从单个逗号拼接的字符串改为 string[]（直接传数组），以配合新的 RunConfig 类型。
示例工具链与配置 flow-examples/package.json, flow-examples/tsconfig.json	在 package.json 中新增 TypeScript 检查脚本 "ts-check": "tsc --noEmit"；新增 flow-examples/tsconfig.json（extends 基础配置，target ESNext，noEmit: true，包含 test/**/*.ts）。

- Around line 182-184: The code calls searchPaths.join(...) which crashes when
searchPaths is a string; update the normalization where searchPaths is used (the
searchPaths variable and the args.push("--search-paths", ...) call) to accept
both string and string[]: detect Array.isArray(searchPaths) and join when it is
an array, otherwise coerce a string input (or ignore empty/undefined) before
pushing to args, so callers can gradually migrate to string[] without runtime
errors.

⚠️ Potential issue | 🔴 Critical

修复 searchPaths 兼容性导致的运行时崩溃。
CI 已报 TypeError: searchPaths.join is not a function，说明仍有调用方传入旧的 string。建议在这里做归一化/兜底，同时逐步把调用方升级为 string[]，避免直接崩溃。

✅ 建议修复

-  if (searchPaths) {
-    args.push("--search-paths", searchPaths.join(","));
-  }
+  if (searchPaths) {
+    const normalized = Array.isArray(searchPaths)
+      ? searchPaths
+      : [String(searchPaths)];
+    args.push("--search-paths", normalized.join(","));
+  }
