fix(cli): resolve ESM module resolution for tsx dev mode

- Remove "type": "module" from apps/cli/package.json to avoid
  ESM/CJS interop issues with workspace packages in tsx dev mode
- Configure tsup to output .mjs files (always treated as ESM by Node.js)
- Rename bin entry from chatlab.js to chatlab.mjs
- Change chatlab web default port to 3100 (serve keeps 3110)
- Fix vite plugin: use pnpm instead of npx for tsx invocation
