feat(preset): add image reading and compaction to sdk-minimal

Reuse read_image and automatic compaction in the standalone profile without
adding SDK slash-command handling. Update profile guidance, upgrade steps,
and startup and recorded-session coverage.

 The shipped [`@deepseek-ai/dsh-sdk-minimal` bundle](../../../packages/bundle/sdk-minimal/README.md) is the complete explicit Cordis tree for this mode. It exposes exactly:
 
 - owner-scoped persistent `bash` on Linux/macOS or `pwsh` on Windows
+- `read_image` for PNG/JPEG/WebP/GIF files, with an image-capable model
+- `working_directory` to inspect or change the Session directory
 
-The bundle does not include `dsh-base`, so every additional row is an explicit profile change. Runtime context, filesystem tools, local instruction discovery, compaction, settings, managed credentials, telemetry, Web tools, subagents, and the full default tool roster are absent. The tree retains SDK startup and JSON-RPC serving, one environment-configured DeepSeek adapter, local execution, and JSONL persistence.

[Automatic context compaction](../../../packages/bundle/sdk-minimal/README.md#model-experience) summarizes older history through an additional model request while preserving the complete log. SDK prompt text does not execute slash commands.
 
 The persistent PTY can modify any path available to the runtime process, so use a disposable checkout or container.

+- 配合支持图片输入的模型读取 PNG/JPEG/WebP/GIF 文件的 `read_image`
+- 查询或修改 Session 目录的 `working_directory`
