Merge remote-tracking branch 'origin/master' into codex/disable-telemetry-default

Resolve three conflicts:

- packages/bundle/base/tests/base.spec.ts: keep both assertion sets — this
  branch's telemetry-otel mode expression and master's subagent rows plus
  manifest dependencies.
- packages/session/session-telemetry-otel/tests/otel.spec.ts: keep master's
  per-mode sharing disclosure test, but select FULL explicitly instead of
  relying on an omitted mode, because the default is now DISABLED; the
  default-construction test keeps asserting disabled delivery and gains a
  case pinning that an omitted mode reports 'disabled' sharing.
- scripts/snapshots/translation-prompt-v4/request-response.expected.json:
  re-recorded from the merged READMEs rather than hand-merging the embedded
  document text.

 Session Logs stay local by default. Set `DSH_TELEMETRY_MODE=FEEDBACK_ONLY` to share a Session Log only when submitting feedback, or `DSH_TELEMETRY_MODE=FULL` to upload continuously; `FULL` also enables dsh-sdk command telemetry reporting an anonymous ID, the command result, and redacted project configuration.

-Clone the repository, then run the installer:
+Clone this repo, complete the [dependency and API-key setup](docs/user/guide/quickstart.md#step-1-install-and-configure-the-api-key), then run:
 
 ```sh
-git clone <repo-url>
-cd deepseek-harness
-scripts/install.sh

 ```
 
-The installer requires `git` and Node `^22.19 || >=24`, offers to install `pnpm` when it is missing, prompts for a DeepSeek API key, builds the required repository artifacts, and launches the Web UI.

-The default active checkout is `~/.dsh/source/current`, and the launcher is linked into `~/.local/bin`. Re-run the installer to update. [`scripts/install.sh`](scripts/install.sh) owns alternate locations, update mechanics, and recovery options.

 ## Use DeepSeek Harness
 
 ### Web UI
 
-For the recommended local interface, choose Web UI when the installer finishes. To start it later, or after updating the active checkout, build the repository and run:
+Start the recommended local interface from the repository root:
 
 ```sh
-(cd ~/.dsh/source/current && pnpm run build)
-dsh web
+pnpm dsh web
 ```
 
-The path above is the installer's default. If you set `DSH_SOURCE` or `DSH_CURRENT`, or reused an existing checkout, replace `~/.dsh/source/current` with that checkout path; see [`scripts/install.sh`](scripts/install.sh) for details. The Web UI is served at `http://127.0.0.1:3080` by default.
+The command builds the repository before starting the Web UI, which is served at `http://127.0.0.1:3080` by default.
