fix(rpiv-workflow): consult the watchdog verdict before the abort stop shape

An abort landing mid-tool does not surface as stopReason "aborted": the
killed bash returns an error toolResult and the loop records the strangled
follow-up request as an empty assistant entry with stopReason "error" (or
the transcript truncates on the tool request — "toolUse"). Gating the
watchdog verdict behind the "aborted" shape sent that exact case to the
stop arm, where "error" reads as infra death and hard-failed the unit
(run 2026-08-20_14-54-40-4cc2, implement phase-1) instead of consuming a
strike. classifyAndHandleAbort now reads the verdict for every non-clean
stop, before the aborted-stop test; a clean stop still outranks a stale
verdict, and non-clean stops without a verdict keep their infra-death
routing.
