DimaS b1be9ed27f fix(daemon): cancel running agent when task is deleted server-side (#2107)
When the server deletes a task while the daemon's agent is still running
(issue removed, agent reassigned, workspace cleanup), GetTaskStatus
starts returning 404 "task not found". The previous polling loop only
checked for status == "cancelled" and silently swallowed the error, so
the local agent kept emitting tool calls against a dead task until its
own timeout fired — minutes of wasted model spend and patch_apply
operations against a workdir nobody would consume.

Changes:

- Add isTaskNotFoundError next to isWorkspaceNotFoundError so the daemon
  can distinguish "task gone" 404 from "workspace gone" 404 (already
  handled separately) and from generic network errors.
- Extract the cancellation polling goroutine in handleTask into
  watchTaskCancellation, plus a pure shouldInterruptAgent decision
  helper. The pure helper makes both signals (cancelled status and 404
  task) easy to unit-test without spinning up a real backend.
- Trigger interruption on the new 404 path. Transient errors (5xx,
  network) intentionally still don't cancel — the next poll will retry
  and a flaky link should not kill an in-flight agent.

Tests cover the helper truth table, the existing "status cancelled"
path, the new "task deleted (404)" path, and a negative case ensuring a
running task is not interrupted.
