docs(agent-notes): revert public beta framing in default-off note

The repo's user-visible copy (root README, welcome notice) still
describes internal testing, so 'entering public beta' was an unrecorded
fact and contradicted this PR's own copy. Problem now states the recorded
facts: internal testing mounted telemetry with a baked-in production
endpoint and both feeds reported by default to help diagnose problems,
so a fresh installation exported without a positive deployment choice.
Consequences returns to the phase-independent statement.

 ## Problem
 
-DeepSeek Harness is entering its public beta phase. During internal testing, telemetry was enabled by default — the session OTel backend and the dsh-sdk launcher both reported without a positive deployment choice — to help diagnose reported issues. For public beta, outbound reporting must require an explicit opt-in from the deployment.
+DeepSeek Harness has two outbound telemetry feeds. During internal testing, the shared base mounted telemetry with a baked-in production endpoint, and both feeds reported by default to help diagnose reported problems: the session OTel backend could export complete session content, tool data, prompts, and workspace paths when its mode was omitted, while the dsh-sdk launcher feed reported by default. A fresh installation therefore permitted outbound reporting without a positive deployment choice.

 ## Consequences
 
-All public beta profiles and projects make no telemetry network request by default — a break from the internal-testing default of reporting when configured. Internal deployments that still need reporting select one mode for both feeds: `FEEDBACK_ONLY` permits only feedback-triggered Session Log sharing, while `FULL` also enables launcher reporting. The existing hard opt-out remains effective, and uploading modes retain their endpoint validation, redaction responsibility, batching, and shutdown behavior.

 ## 问题
 
-DeepSeek Harness 正在进入公测阶段。在内测阶段，遥测默认开启——会话 OTel 后端和 dsh-sdk 启动器均无需部署方明确选择即可上报——以帮助诊断上报的问题。进入公测后，出站上报必须由部署方显式启用。
+DeepSeek Harness 有两路出站遥测数据流。在内测阶段，共享基础配置挂载了带内建生产 endpoint 的遥测，两路数据流默认上报以帮助诊断上报的问题：会话 OTel 后端在省略 `mode` 时可能导出完整会话内容、工具数据、提示词和工作区路径，而 dsh-sdk 启动器数据流默认上报。因此，全新安装无需部署方明确选择便允许向外上报。

 ## 后果
 
-所有公测 profile 和项目默认不发出任何遥测网络请求——与内测阶段配置后即上报的默认行为不同。仍需上报的内部部署为两路数据流选择一个模式：`FEEDBACK_ONLY` 只允许由反馈触发的 Session Log 共享，`FULL` 还会启用启动器上报。现有硬性退出继续生效，上传模式也保留 endpoint 校验、脱敏责任、批处理和关闭行为。
