FSM задачи (Tasks Task, BL-31).

Источник истины — task.entity.ts; машина — xstate v5 spec (ADR-0022), re-export'ится @mineflow/api-schemas для расчёта доступных действий по статусу в UI. Назначение исполнителя (assign/unassign) — ортогонально статусу и в FSM не моделируется.

Состояния и переходы:

open (начальное) → START → inProgress
open → CANCEL → cancelled (guard hasCancelReason)
inProgress → BLOCK → blocked (guard hasBlockReason)
inProgress → COMPLETE → done
inProgress → CANCEL → cancelled (guard hasCancelReason)
blocked → UNBLOCK → inProgress
blocked → CANCEL → cancelled (guard hasCancelReason)
done, cancelled — терминальные. Reopen — отложен в v2 (BL-31 §D5).
