Build and startup improvements: add start script and fix opentypebb dependencies

[greatpie]

Build + Startup Improvements (Production)

Problem

When running the production build (pnpm build) and then starting the server, the app fails with an ESM module resolution error because the internal package @traderalice/opentypebb exports point at src/ instead of built dist/ files.

Additionally, there is no convenient start script for running the production build after pnpm build.

---

Suggested Fix (Markdown + Code Examples)

1) Add a start script to package.json

This allows users to run pnpm start after building.

{
  "scripts": {
    "dev": "tsx src/main.ts",
    "dev:ui": "pnpm --filter open-alice-ui dev",
-    "build": "pnpm --filter opentypebb build && pnpm build:ui && pnpm build:backend",
+    "build": "pnpm --filter opentypebb build && pnpm build:ui && pnpm build:backend",
    "build:ui": "pnpm --filter open-alice-ui build",
    "build:backend": "tsup src/main.ts --format esm --dts",
    "test": "vitest run",
    "test:watch": "vitest",
+    "start": "node dist/main.js"
  },
  "keywords": [
    "trading",
    "ai-agent",
    "crypto",
    "securities",
    "file-driven"
  ],
  ...
}

2) Fix @traderalice/opentypebb exports (point to dist/)

When the root app imports @traderalice/opentypebb, Node resolves the package entry points via exports. The exports currently point at source .ts files, so running the built app fails unless the TS sources are present.

Update packages/opentypebb/package.json:

{
  "name": "@traderalice/opentypebb",
  "version": "0.1.2",
  "description": "TypeScript port of OpenBB Platform — financial data infrastructure",
  "type": "module",
  "exports": {
    ".": {
-      "import": "./src/index.ts",
-      "types": "./src/index.ts"
+      "import": "./dist/index.js",
+      "types": "./dist/index.d.ts"
    },
    "./server": {
-      "import": "./src/server.ts",
-      "types": "./src/server.ts"
+      "import": "./dist/server.js",
+      "types": "./dist/server.d.ts"
    }
  },
  "files": [
    "dist"
  ],
  ...
}

3) Ensure build order includes opentypebb

Make sure the top-level build script builds opentypebb first so the main app can import it successfully.

{
  "scripts": {
-    "build": "pnpm build:ui && pnpm build:backend",
+    "build": "pnpm --filter opentypebb build && pnpm build:ui && pnpm build:backend",
    "build:ui": "pnpm --filter open-alice-ui build",
    "build:backend": "tsup src/main.ts --format esm --dts",
    ...
  },
  ...
}

---

Expected Result

• pnpm build completes successfully
• pnpm start runs the production server on port 3002
• No ERR_MODULE_NOT_FOUND related to opentypebb in production mode

---

Environment

• Node.js 22+
• pnpm 10+
• OpenAlice version: 0.9.0-beta.5
