feat: L0 线协议冻结 + 附件链路修复 + 人/Agent 区分

L0 核心:
- 严格解码 Decode(DisallowUnknownFields) 全覆盖 29 个 DecodeBody 调用点
- DecodeLenient 心跳专用:容忍新字段但回报 unknown_fields
- 400 消息列出本端点接受的全部字段(jsonFieldNames 反射 tag)
- 日历 status 校验(create 补字段 + update 拦非法值)
- 新增 strictdecode_test.go 10 例 + blob/list_test.go 6 例

A-4 附件挂载回滚:checkAttachable 在 CreateMail 前校验,失败按
解挂→释放 relay→删邮件→退预算回滚,幽灵邮件这条路堵住了

A-5 反向 GC:blob.Store.List() 枚举磁盘(跳 .upload-*),
SweepUnreferencedBlobs 按 attachments + calendar_attachments 反查,
48h 年龄下限兜上传窗口。已接进每小时 sweep 循环

C 人/Agent 区分:四个读路径 + threadCols 补 from_human / to_human
(EXISTS users 判定),models.Mail 加 ToHuman。前端判据从
workspace 启发式改成显式布尔,mailCounterpart/sessionCounterpart
从 session_workspace 取 path(修 dsh@dsh 拼接 bug)

契约文档:SSE new_mail 补 4 字段(in_reply_to/from_human/
permission_mode/permission_enforcement),B-5 加 B-5.6
(Agent→Agent 不转发),B-3.4 MUST 改条件式,心跳补 mode_enforcement
+ unknown_fields,demo 死链修复 + from_human 检查
验收清单加 Agent→Agent 负向对照项
