ZiyaZhang 00390ae851 feat(web): open a produced file from the conversation
Serve one file at a time out of a Session's workspace under /f on the web
transport, and point the conversation's existing file-open affordance at it.
Clicking a write/edit/read row's path now opens that file in a browser tab —
including from a LAN client, where the Host's system opener is fenced to
loopback and answered nothing.

- /f/<sessionId>/<segments> in client-connection, behind the same
  browser-trust fence as /api; realpath confinement, streamed reads,
  GET/HEAD only, nosniff + no-store.
- Script-capable documents carry CSP sandbox: model-authored markup must not
  be same-origin with /api, where events.mux is a readable GET stream.
- ApiProxy.workspaceRootOf answers where a Session's files live without
  resuming an agent; the client program cannot reach the core services.
- The /f URL shape lives in dsh-host-apiproxy/api so both ends share one
  encoding (client bundles may not value-import another plugin).

host/ — web-GUI host half

English | 中文

The host side of the dsh web GUI: the API gateway every client shape shares, and the plain HTTP server it rides on. The browser side lives in client/; the composed application is apps/cli serving apps/web. All product packages.

Package Role ctx key
apiproxy/ The shared API gateway: the zero-Node TS wire contract (src/api/), the fetch carrier pair (toFetchHandler host-side, AbstractApiClient client-side), and the host implementation over ctx.agents/ctx.workspace ctx.apiProxy
webserver/ Plain HTTP route-registration carrier: node:http server listening on activation; routes register as named exact/prefix handlers ctx.httpServer
directory-picker/ Workspace-directory picking seam: discriminated native/browse capability the gateway's picker RPCs delegate to ctx.directoryPicker
directory-picker-native/ Dual-face native interaction: OS-chooser backend (osascript / PowerShell / Zenity+KDialog, host-display only) + the browser half filling ui-workspace's directory-flow slots (registers ctx.directoryPicker)
directory-picker-browse/ Dual-face browse interaction: listing/creation primitives over Node stdlib (remote-capable) + the browser half rendering the in-app Select Workspace Directory dialog (registers ctx.directoryPicker)
directory-picker-auto/ Adaptive chooser: resolves the host's situation once at boot (bind host, SSH, display) and mounts the matching dual-face backend as an in-memory Loader entry (mounts a backend row)

apiproxy is transport-agnostic by design — it registers no routes; carriers wrap ctx.apiProxy themselves. The HTTP carrier route (with its /api browser-trust fence) is mounted by client/connection's node half, which is why that package lives in the client group: it owns both ends of the wire.
