FN-7977: hold Plan Review provider failures without replan regression
Prevent provider, model, transport, and abort failures from bouncing tasks back to planning after they enter execution.
- Classify non-plan-defect Plan Review failures and skip needs-replan handoff
- Terminate graph traversal with plan-review-provider-failure-hold and retry in place
- Guard triage recovery so advanced column/worktree/step state is never overwritten
- Document planning-recovery no-regression invariant and add regression tests
- Add patch changeset for the operator-facing fix
