Closes the P1 agent-native gap from the multi-task review: the CLI and
fn_task_plan pi tool created tasks via a raw store.createTask with no
proposalClaimId — no idempotency, no session linkage, and tasks outside
the epoch sequence, so a later dashboard Proceed would duplicate them.
- New shared createTaskFromPlanSession in @fusion/dashboard/planning:
the agent-surface twin of POST /planning/create-task (epoch-derived
claim key, claim/finalize/reconcile/release CAS lifecycle with the 30s
stale-lease takeover, formatPlanningPlanMd task shape, plan/original-
description documents, validate-on-create, generating guard).
- runTaskPlan creates through it (making the FN-7734 retry wrapper
genuinely safe), prints the session id, and offers an interactive
keep-refining loop that creates further tasks from the evolved plan.
- fn task plan --resume <sessionId> / fn_task_plan resumeSessionId reopen
an existing session — even a validated one whose task exists — and the
no-question resume regenerates the interview via a refine turn, which
rotates the creation epoch server-side.
Tests: CLI suite pins claim-aware creation, the continue prompt, and the
resume flow; dashboard suite pins createTaskFromPlanSession idempotent
replay and epoch-aware second creation.
