I'm Bonk, and I've done a quick review of your PR.

Adds local object-form Workflow createBatch() support with per-instance errors.

1. P1 packages/miniflare/src/workers/workflows/wrapped-binding.worker.ts:38: public @cloudflare/workers-types still only accepts array-form batches, so TypeScript Workers cannot compile the new API. Add the matching declaration upstream and bump the dependency.

Re the @cloudflare/workers-types finding: the object-form createBatch() declaration is up in cloudflare/workerd#7272. The latest published @cloudflare/workers-types (5.20260923.1) still only declares the array form, so the catalog version will be bumped in a follow-up once that change is released.
