task-progress-config.ts 新增 getTaskPollBackoffMaxMs()（默认 10000， 由 5000 提升）与 getTaskPollBackoffFactor()（默认 2，<1 钳制为 1）； configureTaskPolling 支持 backoffFactor；getTaskPollBackoffMs 改用 base × factor^attempt 计算。 既有 task-086 边界测试中封顶 5000 的快照随新默认更新为 10000。 新增 8 个测试：max/factor 默认、可覆盖、非正钳制、factor 下限、 配置隔离、默认值快照。
