重构回忆录为 story-first / markdown-first 架构并整合图片意图与前端 UI 修复

本次 squash merge 将 codex-story-first-image-intent 的整体改动合入 development,核心内容包括:

1. 后端数据与迁移:新增 stories、story_versions、story_image_intents、chapter_cover_intents、assets 等模型与 Alembic 迁移,建立 story-first、markdown-first、asset-first 的主数据链路。

2. 生成与任务链:引入 StoryBuilderOrchestrator、ChapterComposerOrchestrator、story_image_tasks、chapter_cover_tasks,图片生成从正文占位符改为结构化 intent -> asset -> markdown 回填。

3. 并发与一致性:为 story/chapter intent 增加 claim_token、claimed_at、attempt_count,采用数据库原子 claim 为主、Redis 锁为辅,避免重复生成、锁误删和 processing 卡死。

4. Memoir 读写路径:章节 canonical_markdown 成为正文真源,列表/详情接口补齐 markdown、cover_asset、word_count 等字段,PDF 与 asset 解析链路同步升级。

5. Memory / Retrieval:扩展 transcript ingest、chunking、evidence 检索与 story 聚合基础设施,为后续 story-first RAG 与多 agent 编排提供底座。

6. App 端体验:章节页继续走 MarkdownRenderer 阅读链,同时吸收 fix3-19 的跨平台 UI glitch 修复;更新对话页、首页、文案资源与章节列表映射逻辑。

7. 测试与文档:补充 asset resolver、story image task、章节封面派发、markdown 映射等回归测试,并加入图片占位符退役设计文档。
