The task cards already show Retry for needs-replan/planning/failed states, but
the retry route only offered the planning retry when the card sat in "triage",
so plan-in-place workflows (Coding (Ideas) replans in Todo) got a 400 "not in a
retryable state". The retrySpecification gate is now workflow-aware: a Todo card
whose workflow declares no "triage" column takes the planning-retry path;
default-workflow Todo cards keep the generic-retry semantics.
