Multica Eveandmultica-agent 79d801f45c MUL-8188: fail fast on Kiro panic and stop resuming undrivable sessions (#9458)
* fix(kiro): fail fast when the runtime panics mid-turn (MUL-8188)

Kiro can panic inside its agent loop while the ACP process stays alive, so
session/prompt never answered and the task hung until the 2h idle watchdog
or a manual cancel. Watch stderr live for a panic header, abort the prompt,
and surface the panic text. A resumed session that panics before its first
message signals ResumeRejected so the daemon retries once on a fresh session.

* fix(resume): stop re-resuming sessions the runtime cannot drive (MUL-8188)

- taskfailure.UnresumableHistory matches "invalid conversation history",
  so the daemon's fresh-session retry, classifyPoisonedError and
  ResumeUnsafeFailure all treat Kiro's panic as resume-unsafe; the
  GetLastTaskSession / GetLastChatTaskSession text guards mirror it for
  rows written by older daemons.
- A resumed run cancelled after >=5 minutes with zero agent output now
  retires its session: the daemon sends retired_session_id on cancel-ack
  and the server records it on the cancelled row (status CAS, never
  overwrites) and clears a chat pointer still naming it.

* fix(resume): address review on retired sessions (MUL-8188)

- Manual retry no longer revives a retired session: the exact-source rerun
  claim path now checks IsTaskSessionRetired (fails closed), still reuses
  the source workdir, and sets PriorSessionResumeUnavailable.
- Silent-resume retirement measures awakeclock time, so host suspend
  (Windows monotonic clock counts through sleep) cannot retire a healthy
  session; adds a suspend regression test.
- Handler tests use dbfx.Issue/Task and testutil.Call per AGENTS.md.
