feat: complete HomeAgent architecture v2

- IO abstraction layer with OutputChannel routing and capability validation
- Three-layer memory (Context-Document-Graph) with TF-IDF relevance pruning
- OneBot V11 QQ protocol plugin with Reverse WebSocket client
- Plugin system with hot-reload (SKILL.md + native factories)
- Knowledge system with TF-IDF vector indexing
- Personality system (personal.md)
- Text memory (JSONL with rotation)
- Change tracker (overlayfs) with rollback
- Lua adapter VM
- Design document (DESIGN.md)
