Chinesezjc b462d5fd69 Merge remote-tracking branch 'origin/master' into feat/web-message-feedback-ui
Adapt to two contract changes master introduced:

- The generated Remote face now wraps every business result in
  RemoteResult, folding carrier failures into an ok:false branch instead
  of rejecting. The controller reads that envelope at its three call
  sites and maps a carrier failure onto the same settled shape the
  controls already render; three specs cover the new branch.
- Client packages split their tsconfig into host and client halves, and
  the host aggregate now compiles any test not named *.client.spec.*.
  Rename this package's specs to the client convention and drop the
  ../connection project reference, which pointed at a solution file that
  no longer carries the client sources.

Keep master's mount loop with its rollback-on-failure in api-remotes and
add messageFeedbackRemote to it.

@deepseek-ai/dsh-host-directory-picker-native

English | 中文

The native-OS-chooser backend of the directory-picker seam: NativeDirectoryPicker registers ctx.directoryPicker with the native capability, whose pick(signal) opens one native chooser per call and resolves the chosen absolute path (null on cancel). Platform tools run without a shell: osascript on macOS and Zenity with a KDialog fallback on Linux; the caller's abort terminates the native process. Windows opens the modern IFileOpenDialog in a spawned child process — a koffi-driven COM conversation on the child's main thread with the best thread DPI awareness the host accepts (per-monitor-v2 first), aborted by posting WM_CLOSE to the dialog thread. Only viable when the operator sits at the host's display — remote deployments compose -browse instead. The command boundary (DirectoryPickerRunner) and platform facts are injectable. The shared no-shell subprocess runner lives in dsh-native-command.

Dual-face package: the browser half (./client) registers a renderless flow occupant into ui-workspace's two directory-flow holes — each open request drives host.pickDirectory and reports the one outcome (picked path / cancel / failure) through the hole's owner conversation. Both directory-flow declarations must be live before either contribution installs. One cordis.yml row therefore composes both sides of the native interaction; the client carries no capability-kind branching, and mounting a second flow package fails at load (the holes are single kind).

Model Experience

None, as the backend serves the GUI host's directory selection; nothing here reaches a model request.

KV Cache effect

None; this package neither assembles nor sends a provider request.

Known Limitations and Deferred Work

  • Linux requires desktop tooling — with neither Zenity nor KDialog installed, pick rejects with an actionable error; it does not fall back to a typed-path prompt (the browse backend is that fallback at the composition level).
  • Windows has no mechanism fallback — the child-process picker through packaged koffi is the only native tier, so a COM refusal or dialog crash surfaces the failure. The browse backend remains the fallback at the composition level.
