A completion the server rejects leaves the batch it staged under a token no marker will name. When History already says the task failed, the Worker aborts that stage at eviction instead of leaving it for a reader to find. A stage History committed stays pending for the client's repair.
A batch staged for a rejected task leaves the shared log once the Worker evicts the run, so an outside reader never meets it.

This PR aborts a rejected task's staged output when the Worker evicts its run.
What changed?
Part of AI-198 (epic AI-37).
Why?
A completion the server rejects leaves its batch under a token no marker will ever name. Before this, nothing settled it until a reader hit the barrier. On a provider whose workflow and producers share one log, those entries count against every window. This change is worker code, but its only test needs the Redis provider's shared log, so it sits after the Redis PRs.
How did you test it?
Link to a test plan if any -
poe lintis clean. The external stream suite passes on the dev server. The streams suite withSTREAMS_LIVE=redispasses against a channel server and a local Redis, with the linked kind on and off.
