chore: Add commonjs builds to openinference-genai

[cephalization]

Import and require appear to both work in my sample repo. require does not get type information though, users will need to write esm and compile/execute to commonjs for typings (which is common).

In addition will need to bump https://github.com/mastra-ai/mastra/blob/d7509c2b59f3772a91c8f32c37b9e93b64c7da7d/observability/arize/package.json#L34

---

Note

Add CommonJS build and dual ESM/CJS exports for @arizeai/openinference-genai, updating build scripts and TS configs, with a patch changeset.

• Build/Packaging:
  • Add CommonJS build via tsconfig.commonjs.json; update build to compile both CJS and ESM.
  • Enable dual exports in package.json with "require" entries for ., ./attributes, ./utils, and ./types; set "main" to dist/src/index.js, "module" to dist/esm/index.js, and update "types".
  • Adjust ESM/TS configs: use module: "preserve", moduleResolution: "bundler", set noEmit and tsBuildInfoFile paths.
• Release:
  • Add changeset for a patch release of @arizeai/openinference-genai.

Bug: Main and types fields point to non-existent paths

The main and types fields point to dist/src/index.js and dist/src/index.d.ts, but the build script only generates output to dist/commonjs/ and dist/esm/ directories. The tsconfig.commonjs.json has outDir: "dist/commonjs" with rootDir: "src", so files compile to dist/commonjs/index.js. The dist/src/ directory will never be created, causing Node.js to fail to resolve the package when these fallback fields are used.

Bug: Require condition points to type definition file instead of JavaScript

The require condition for the ./types export points to ./dist/commonjs/types.d.ts, which is a TypeScript declaration file, not executable JavaScript. When CommonJS consumers use require("@arizeai/openinference-genai/types"), Node.js will attempt to load the .d.ts file as JavaScript and fail. The require condition needs to point to a .js file (e.g., ./dist/commonjs/types.js).
