The release goroutine used the workflow ctx, which is cancelled right after the request returns. This can kill the release call before it runs, leaving the worker stuck with a stale assignment.

This change definitely makes sense to me, I'd love Julian Gutierrez Oschmann (@juli4n) or Zoe Zhao (@zoez7) to take a look as they are more familiar with this path

AssignWorkerStep starts a background goroutine to release a stale
worker assignment. It builds its context from the request ctx, but
that ctx is cancelled right after the workflow returns (releaseLock
runs on defer). If the goroutine has not called UpdateWorker yet, the
call fails with a cancelled context and the worker keeps the stale
assignment forever. Nothing else clears it while the pod is alive.
Fix: use context.Background() for the release call, same pattern used
in cmd/atenet/internal/router/resumer.go.
Tested with go test ./cmd/ateapi/internal/controlapi/...
