Reproduction for sentry-javascript#19883

Bug: instrumentWorkflowWithSentry from @sentry/cloudflare swallows the WorkflowStepContext (ctx) parameter in step.do callbacks, making ctx.attempt (and any future context properties) undefined.

Root cause: WrappedWorkflowStep.do in packages/cloudflare/src/workflows.ts:

1. instrumentedCallback is typed as () => Promise<T> — drops the ctx arg passed by the real step.do
2. userCallback() is called with zero arguments — doesn't forward ctx

How to run

cd sentry-javascript/19883
node repro.mjs

Output

=== Without Sentry instrumentation ===
  ctx: { attempt: 1 }
  ctx.attempt: 1
  returned: 1

=== With Sentry instrumentation (WrappedWorkflowStep.do) ===
  ctx: undefined
  ctx?.attempt: undefined
  returned: undefined

BUG CONFIRMED: Sentry wrapper swallows ctx — ctx.attempt is undefined.
