feat: Phase 1+2 架构进化 — 连续思考链/主动消息决策/情感状态机/离线自主思考 (86文件)

Phase 1 (基础设施):
- ThinkChain 思考链连续性 + 差异化思考提示词 (persistent)
- AutonomousToolPolicy 工具安全策略 (safe/unsafe/conditional)
- MessageScheduler 自适应消息节奏 (Idle/Available/Busy)
- SessionEnrichmentStore 渐进式上下文丰富 (5层)
- ConversationBus 事件总线 + ResponseCache (dedup)
- pkg/logger 统一日志 + 所有 handler 替换 fmt.Printf
- NPE 守卫/链路优化/数据库表修复/Go workspace

Phase 2 (人格交互):
- EmotionState/EmotionTracker 情感状态机 (5种心情, 情绪衰减)
- ProactiveGuard 主动消息多维决策 (静默时段/紧急度/频率/校验)
- Gateway↔ai-core 在线状态感知链路 (presence notification)
- 离线思考频率控制 + 重连问候 + 离线消息排队
