feat(emotion): A1 情绪系统接线 + refactor: 拆分 channelbridge.go

A1 情绪接线:
- loop 回合边界钩子(TurnEnd/OnTurnEnd/settleTurn, Result.Mood); 每轮一次非每步
- persona/emotion: React(valence五档) + Machine.Move(BFS最短合法路径一步) + Observer(observe/decay/好感度,仅变化才emit); 好感度步长读角色配置(cyrene delta=10, 0..700)
- 落库 Mood(web session_persist.res.Mood + IM channelbridge/persist; user消息不带mood); WS mood事件(BroadcastMood,仅变化); per-persona隔离; 群聊/陌生人只读不写不发
- cmd/cyrene/emotion.go 生产接线 + wire.go 注入 loop.Options.OnTurnEnd
- 22 测试(状态机被loop调用/Mood非空落库/mood帧shape/只变化才发/群聊只读) + 真二进制冒烟
- Docs: api-client v0.32 §3.7 情绪事件 + 开源对照清单(companion 应用对照)
- 诚实: 本机无LLM凭据→未活体验证'模型返回后完整轮次'一环

拆分 channelbridge.go 816→257(纯搬移零逻辑): connect/inbound/outbound/blacklist/helpers.go; A1 的 IM mood 调用点落在新 inbound.go, 故与本提交同批

回滚 6 个 gofmt 顺手格式化文件(capacity_loop_test/flow/source_test/findchannel_test/admin_channels_platform_test/history) 缩 diff, 含 history.go 注释被转弯引号
