Task Persistence

· v1.1.0

High Risk

Task continuity, session snapshots, and gateway restart recovery. Use when starting long-running tasks (register them), after gateway restart (check for interrupted tasks), or when user asks about task status/recovery. Trigger on "resume", "任务恢复", "重启后", "未完成任务", or before/after any multi-step operation.
