- Task 增扩展列：publisher_role/visibility/c_visible/park_public/assign_type/assign_park_id/assign_opc_id/park_id/park_released/bid_quota/win_quota/eligibility(JSON)/settle_mode(默认operator_escrow)
- TaskRepository._to_dict/create/update 同步新字段；迁移 0020_task_multi_mode
- TaskService.can_accept(task,user)：仅被指派/园区专属/指派园区未发单 + eligibility(证书/地域/性别/工时/领域/专长/案例) 判定，返回 ok/reasons
- 抢单(grab)与投标(bid)接入 can_accept 守卫；bid 加报名上限与重复报名校验
- /opc/tasks 公开广场改为 published+c_visible；/opc/tasks/{id} 详情同；登录后附带 can_accept/accept_reasons(经 optional_current_user)
