Bug Description

The Typescript SDK: @anthropic-ai/claude-code does not export types

Steps to Reproduce

Try to use:

import { query, type SDKMessage } from '@anthropic-ai/claude-code';

Expected Behavior

No errors

Actual Behavior

Typescript is unable to resolve the correct type and errors with:

Could not find a declaration file for module '@anthropic-ai/claude-code'. '/Users/brian/gt/gt-libraries/node_modules/@anthropic-ai/claude-code/sdk.mjs' implicitly has an 'any' type.

Additional Context

Adding
"types": "sdk.d.ts",
to the package.json fixes the issue
