fix(cloudflare): Forward ctx argument to Workflow.do user callback

[Lms24]

This PR fixes a bug in our Cloudflare Workflows instrumentation where we didn't forward the recently introduced ctx argument to users' Workflow.do callbacks. We now pass all ...args from the workflow through our instrumentation to the user callback.

LGTM. A reminder to ourselves that this could happen anytime. It might make sense to always just forward all callback arguments in Cloudflare when there is something like that to be future proof.

Agreed! I had Cursor go over the cloudflare SDK and look for similar occurances but we usually pass all args. Worth noting that we use Reflect and Proxy in most other instrumentation. We could look into aligning workflows here though I'm not sure if there's a specific reason we're breaking pattern here.

Based on the analysis, this was the only occurance where we didn't pass in arguments. We can follow up with a better audit but for now I think we're good.
