适配 DeepSeek Harness dsh-v0.1.3-alpha.1，修复转换图片的会话归属，并恢复与原生通用文件上传的共存。
- 通过 ctx.get('conversation') 读取宿主服务，使用 createDrafts(sessionId, files)、addAttachments 和 releaseDraftAttachments；保留旧版图片接口兼容。
- 移除全局合成 drop 兜底；接口不可用或拒绝时明确提示并释放新建附件，不再误报成功。
- ZIP 等无需转换的文件整批放行；混合批次将转换图片与原生文件挂入开始处理时的会话。
- 文档卡片、转换进度、剪贴板文字按会话隔离，切换会话不会覆盖另一会话的附件。
- 浏览器产物隔离顶层变量，支持宿主重新加载；兼容性检查加入 dsh-v0.1.3-alpha.1。
English
Restore attachment compatibility with DeepSeek Harness dsh-v0.1.3-alpha.1. Converted images and mixed native files attach to their original session through the new conversation service, while legacy image interfaces remain supported.
- Use ctx.get('conversation'), createDrafts, addAttachments and releaseDraftAttachments.
- Remove global synthetic-drop fallback; report rejected attachments and clean up drafts.
- Let native-only batches pass through, including ZIP files, and route mixed batches to the original session.
- Preserve document cards, progress and clipboard text independently for each session.
- Isolate browser bundle globals for host reloads and extend the upstream compatibility matrix.
Validation / 验证
- Converter, route, client, OCR and P0 smoke suites passed locally; pandoc and LibreOffice checks skipped because those optional programs were not installed.
- Type checking, lint and focused final client regressions passed.
- Real Harness 0.1.3-alpha.1 browser acceptance covered SVG-to-PNG conversion, native ZIP upload with verified contents, document merge and session navigation. Model responses were not tested: the isolated fixture had no provider credentials.
- Update the plugin, restart dsh web and refresh the browser to load the new bundle.
GitHub Actions passed on the release commit: Node.js 22/24 CI and Harness compatibility for 0.1.1-rc.2, 0.1.2-alpha.1 and 0.1.3-alpha.1.
