Minor import clean-ups (#2132)

 > [!NOTE] > Updates AI SDK imports to use the top-level `ai` package instead of `node_modules/ai/dist`. > > - In `prepare_step_utils.ts` and its tests, replace imports of `ImagePart`, `ModelMessage`, `TextPart`, and `UserModelMessage` to come from `ai` > - No functional code changes beyond import paths > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 117078577aa8f7a86564f8a133c2708601f4acb1. This will update automatically on new commits. Configure [here](https://cursor.com/dashboard?tab=bugbot).</sup>   ## Summary by cubic Replaced deep imports from node_modules/ai/dist with the ai package entrypoint to standardize and simplify module imports. This avoids brittle paths and improves build compatibility. <sup>Written for commit 117078577aa8f7a86564f8a133c2708601f4acb1. Summary will update on new commits.</sup>
