wangdl fe44dec567 feat: M-CHAT ChatScope 会话系统完整实现 ...

## 数据模型
- ChatSession +13 字段 (scopeType/scopeId/parentKnowledgeBaseId/createdFrom/isPinned/isArchived/isDeleted/modelMode/modelId/lastMessageAt)
- ChatMessage +scopeSnapshot (消息级 scope 快照)
- ChatCitation +lineStart/lineEnd +sourceId 索引
- 5 个新查询索引

## 核心能力
- open-or-create: 同 scope 继续会话 (200) / 新建 (201)
- scope 级检索: global/knowledge_base/material/knowledge_item/folder
- listSessions: scope 过滤 + isDeleted 排除 + isPinned 排序 + 分页元数据
- 自动标题: 首条消息截取 + 词边界处理
- 软删除 + 置顶/归档
- scope 字段创建后不可修改
- 全部端点 userId 鉴权

## 文档
- docs/chat-scope-design.md (设计文档 + 决策表)
- docs/chat-scope-api-contract.md (API 契约)
- docs/chat-scope-test-plan.md (33 条测试用例)
- prisma/migrations/backfill_chat_scope.sql (旧数据回填)

## Bug 修复
- #104: KnowledgeItem.sourceRef 填充 (material scope 检索修复)
- #102: sendMessageStream aiGateway null 保护
- listSessions isDeleted/isArchived 过滤 + 分页
