多轮图片记忆:
- 此前历史轮次的图片不回传 LLM（attachments 仅存压缩 preview，历史组装
时被丢弃）— 跨轮对话中模型对图片内容"失忆"
- 修复：SessionSummaryService.buildHistoryMessages 从持久化的 attachments
恢复 images（type=image 的 preview base64），历史图片随上下文回传
- Token 控制：最多注入最近 10 张（MAX_HISTORY_IMAGES，从最新消息向前
收集）— 每张 1024px 压缩图约数百至千余 token，无上限会吃满上下文
- 摘要区间（summarizedUntilRowid 之前）的图片不恢复，符合滚动摘要语义
多模态总开关 llm.multimodalEnabled（默认关闭）:
- 新配置项：CONFIG_DEFAULTS 种子 + 设置弹框 LLM 配置 Switch +
首次引导向导 LLM 步骤 Switch（含说明文案）
- 上传入口双重判断：总开关 × 模型能力 — 未开启时即使模型支持多模态
也不能上传图片（ChatInput 的选择/拖拽/粘贴统一拦截，Toast 区分
"开关未开启"与"当前模型不支持"两种原因）
- 保存成功后同步 Agent Store 立即生效；App 启动时随 setProvider 加载
DeepSeek vision 模型支持:
- 新增 deepseek-v4-flash-vision-exp（OpenAI image_url content parts 格式，
128K 上下文 / 8K 输出）
- adapter 按 isVisionModel() 判断：vision 模型将带 images 的消息转换为
[{type:'text'},{type:'image_url'}] parts；非 vision 模型保持 images
静默丢弃（防 API 400）
测试（236 → 243 用例）:
- 多轮图片记忆 ×3（session-summary.test.ts）：历史 attachments 恢复
images / 上限 10 张从最新向前 / 摘要区间图片不恢复
- DeepSeek vision 请求格式 ×4（deepseek-vision.test.ts，契约级 mock
fetch 断言请求体）：image_url parts 转换 / 非 vision 模型丢弃 /
max_tokens 钳制 8192 / 无图不转换
- 测试顺序修正：多轮图片用例置于 describe 末尾（插入新行消耗全局自增
rowid，插在中间会破坏既有用例对 rowid 数值的断言）
文档: README 同步（DeepSeek 模型表 + vision 多模态列、llm.multimodalEnabled
配置项、多轮图片记忆特性行、243 用例数）
验证: lint 0 / typecheck 双工程 0 / test:electron 243 全过 / build 成功
