Add agent timeline ingestion for OpenClaw and Hermes

[starboyate]

Summary

• Make rawdata-agent profile-aware so general agent timelines can reuse the existing agent_timeline pipeline without introducing a new rawdata type.
• Refactor OpenClaw automatic ingestion to buffer lifecycle events and flush completed agent_timeline raw data.
• Refactor Hermes automatic lifecycle ingestion to submit agent_timeline raw data while keeping explicit text extraction as standalone conversation content.
