Upgrades an app from Workflow SDK 4.x to 5.0. Use when bumping the `workflow` / `@workflow/*` dependencies to v5, or when hitting removed v4 APIs — `runStep`, `stepEntrypoint`, `workflow/internal/private`, `@workflow/core/private`, `writeToStream` / `closeStream` / `readFromStream` on a World, `world.steps.get` without a runId, `hook.getConflict()` returning `{ runId }`, `hook.metadata` read synchronously off a `getHookByToken()` result, `experimental_setAttributes`, `createLocalWorld` / `createVercelWorld`, `NestLocalBuilder` imported from `@workflow/nest`, or an SWC transform invoked with `mode: 'client'`.
