creatixchu 9f37ca2709 fix(client,host): late duplicate-provider conflicts roll back wholesale and fail loud

Holes declared after two flow providers activated left the loser throwing
out of the slot flush with partial occupancy. deferRegistration gains an
onFailure channel (late failures unsubscribe, then hand over instead of
throwing through the flush); the native flow's pair rolls back wholesale
and re-raises on the global channel the boot's fail-loud handler owns.
Duplicate rows of the SAME package stay silently idempotent (the component
identity guard skips an occupied hole).

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, an STA PowerShell FolderBrowserDialog on Windows, and Zenity with a KDialog fallback on Linux; the caller's abort terminates the native process. 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 for deterministic tests. 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. 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).
