Omit duplicate wf error in first invocation & not found in cleanup

[CahidArda]

There are cases where network errors cause workflow runs to fail.

This PR handles three of those cases:

1. when the workflow is first created, it is possible for request to fail even though it is delivered to QStash. So QStash creates the workflow but the SDK retries. Solution is to omit this error.
2. when the SDK attempts to delete the workflow run after it completes, the request may fail even though it was delivered to QStash. Solution is to omit this error if it occurs.
3. The workflow endpoint can get an error after scheduling the next step. In this case, the scheduled request may complete the workflow and finish it while the request (which failed) retries after the workflow is finished. We omit the workflow-canceled error to fix this issue.

In both cases, the debugger will log warnings.

this won't be merged right away. We will get a canary release from this branch to verify the solution. If all looks good, we will merge to main.

we should update client.trigger in this PR too #18

can't pass the tests because they are too flaky. we had passed the tests in 51b71eb, and after that change we only bumped qstash and updated how we check omit error cases.

The unit tests pass. I ran the integration test which fails locally and it works. We can go ahead without the CI.
