Merge pull request 'refactor(vision): v8 叙述优先架构大简化' (#2237) from refactor/vision-v8-narration-first into develop

- image_analysis v8 prompt 重写：summary_markdown 自然叙述为主交付，结构化字段仅 type/name/brand/has_person，顶层 products 改 images
- assembler 1017→106：删除 brand 多级兜底与 colors/material/key_features 等全部细分字段处理，summary_markdown 兜底仅一句
- _prompt/fast_path/vlm_* 同步瘦身，删除 prompt 拼接旧 schema 与逐字段处理
- viral_video 删除 _step_intent_parsing（与脚本生成合并为一次 LLM 调用），intent_result 字段保留兼容老数据
- 脚本后处理仅 JSON 解析+基本字段补全，不改 LLM 文案；shots 保留供前端编辑
- storyboard v3 prompt 风格重写：口播口语化、画面有画面感、copy_display_markdown 流畅叙述
- 前端删除 vv-recog-line 全部硬编码字段，统一 markdown 渲染，编辑区不动
- 老数据 products→images 仅在读入时一次性转换，不保留双套逻辑
- Migration 105：重写版 v8 active / v7 deactivate，storyboard v3 更新
- 更新 vision 单测适配新格式

净减少约 1600 行

+背景：
+- qwen-vl-plus 做图片识别时返回 JSON 约 500-600 tokens，旧硬编码
+  max_tokens=350 导致 JSON 被截断、解析失败返回"未识别"。
+- 代码侧已移除硬编码，改由 capability 的 DB 配置决定 max_tokens。
+
+幂等：
+- qwen-vl-plus 已存在则不插入；
+- 仅当 image_analysis 当前 primary_model 不是 qwen-vl-plus 时才更新绑定，
+  避免覆盖后台手动配置。

+
+变更：
+1. image_analysis v8：用「叙述优先」版整体替换 104 的 append 版——VLM 主交付物是
+   自然叙述 summary_markdown，结构化字段仅保留 type/name/brand/has_person，
+   顶层 products 改名 images；v8 active，其余 image_analysis 全部 deactivate。
+2. storyboard v3：整体替换为风格重写版（口播口语化、画面有画面感、
+   copy_display_markdown 流畅叙述）；v3 active，其余 storyboard deactivate。
+3. intent_parsing 类型模板全部 deactivate（意图解析步骤已删除）。
+模板内容直接取自 packages.application.viral_video.prompts.DEFAULT_TEMPLATES，
+保证代码默认值与 DB seed 完全一致。

-1. 违规词：有没有平台禁用词、敏感词。

-3. 事实一致性：有没有编造价格、数据、认证，或者用户没提到的产品特性。
-4. 用户意图保留：在 ai_polish 和 user_primary 模式下，core_messages 中 must_keep=true 的点是否都保留了。
-5. 结构完整性：标题、钩子、正文、行动号召是否齐全。
-6. 语气人设：是否符合选定的人设语气，有没有“家人们谁懂啊”“绝绝子”“宝子们”等套路词。
