docs(sdk): clarify native command input and ordering

Record empty-input migration and canonical-name limits. Verify strict
alias rejection and command notifications preceding query responses.

 Each call subscribes before sending and releases its subscription before returning or raising. `on_notification` receives the ordinary activity interval in wire order; command callbacks replay Session-tree notifications from subscription through their own `command/done` after the command response, so that interval can include overlapping work. Calls may overlap without consuming each other's results. Handler refusals return `CommandExecution.result.kind="error"`; routing, protocol, transport and observer failures raise. A timeout or observer failure does not roll back runtime work or authorize an automatic retry. `request_timeout_seconds` bounds the protocol response wait, not later ordinary prompt activity.
 
-The default full `sdk` profile provides the supported native commands; `sdk-minimal` keeps unsupported input on its ordinary prompt path. `/compact` can make an auxiliary model request and completes without a normal turn or idle notification; empty history can succeed without a summary. The lower-level `HarnessClient.session_command(session_id, line)` executes supported command names without prompt fallback or attachments. See the [compaction example](examples/README.md#compact-a-full-sdk-session).

The lower-level `HarnessClient.session_command(session_id, line)` accepts only supported canonical English command names, without prompt fallback or attachments. Use `run()` for Chinese aliases. See the [compaction example](examples/README.md#compact-a-full-sdk-session).
 
 `/permission <preset>` changes only the receiving Session. An unknown preset returns a command error without changing policy. Later input and restoration retain successful changes; other Sessions and the caller's `DeepSeekHarnessConfig` keep their own values. A running approval-policy change can inject a notice and cause another model step. See the [permission example](examples/README.md#change-session-permissions).

 每次调用在发送前订阅，并在返回或抛出异常前释放自己的订阅。`on_notification` 按线上的顺序接收普通活动区间通知；命令回调在命令响应到达后，按顺序交付从订阅时刻到自身 `command/done` 的 Session 树通知，因此该区间可能包含重叠工作的通知。调用可以重叠，不会消耗彼此的结果。处理器拒绝返回 `CommandExecution.result.kind="error"`，路由、协议、传输和观察回调失败则抛出异常。超时或观察回调失败不回滚运行时工作，也不授权自动重试。`request_timeout_seconds` 限制协议响应等待，不限制之后的普通提示词活动。
 
-默认的完整 `sdk` profile 提供已支持的原生命令；`sdk-minimal` 将未支持的输入保留在普通提示词路径。`/compact` 可以发起辅助模型请求，其完成不需要普通 turn 或 idle 通知；空历史可以在不生成摘要时成功。底层 `HarnessClient.session_command(session_id, line)` 严格执行支持的命令名，不回退为提示词，也不接受附件。见[压缩示例](examples/README.zh.md#compact-a-full-sdk-session)。
