fix: preserve topic tasks across session restarts

[hijzy]

Summary

• Preserve interrupted or paused topics across Hermes/OpenClaw restarts so same-topic turns continue in one task.
• Route recovered open topics through rule + LLM relation classification before finalizing or appending.
• Update Tasks UI/status metadata and regression coverage for interrupted topics, Hermes lazy turn start, and topic-based E2E behavior.
