Chinesezjc bbe1481a9e fix(web): keep escapes, UNC roots, and truncated cwd honest
Four review findings. Two are defects the previous two rounds introduced,
which the existing tests did not catch:

A backspace erased raw bytes, so one landing after an SGR reset ate part of
the escape: `\x1b[31mabc\x1b[0m\b\bXY` left `\x1b[` and repainted the rest of
the line with whatever the remainder parsed as. Backspaces now resolve over
VISIBLE characters — a CSI sequence is one indivisible unit a backspace steps
over on its way to the last printed character, so the surviving text keeps
the color its run authored.

The cwd normalizer popped a UNC share root: `\\server\share` with a `..`
became `/server`, losing the separators too. A UNC path's server and share
are its root, and Windows cannot climb above a share, so they are split off
and the remainder collapses against that root.

The other two are gaps the earlier fixes left:

The render-site fallback row still passed the args-derived summary, so any
terminal-declaring tool without its own keyed row (`terminal_send`) lost the
contract's above-card description. It now prefers the description exactly as
BashRow does.

A settled call read `call?.cwd`, which cannot tell "the call omitted a cwd"
from "the paging window dropped the call head". The second case has no cwd
anywhere and the original call may have used an explicit workdir, so it now
draws a bare `$` instead of naming the session workspace.

client/ — web-GUI browser half

English | 中文

The browser side of the dsh web GUI: shell kernel, module system, wire consumer, React-free object services, the slot system, and the ui-* feature-plugin roster. Authoring rules live in AGENTS.md; the host half is host/. All product packages, named @deepseek-ai/dsh-client-<name>.

Package Role ctx key / slot
web/ Shell kernel: AppWebEntry runs the two-stage boot over the host-pushed entry graph (boots the tree)
modules/ Client module system: browser peer of Node's ESM loader as a lazy CJS table under the vendored cordis Loader (module face)
web-react/ Shell-side React glue: createSlotRenderer + SessionProvider render seats (renderer install)
connection/ Wire consumer both ends: browser ctx.connection (shared api client + stream loop) and the node half mounting the /api route with its browser-trust fence ctx.connection
runtime/ Client cordis boot and React-free object services: slots, Sessions, Workspaces, per-session bindings ctx.slots ctx.sessions ctx.workspaces
hmr/ Dev-only hot reload for fetch-arrival client plugins (--dev graphs) (dev entry)
locale/ Browser locale preference (zh/en) plus the ns×locale dictionary registry ctx.locale
ui-slots/ Slot registry pure core: SlotMap merging, single register API, the four-share props family (types + core)
ui-theme/ Theme preference over the --dsw-* token stylesheets (light/dark/system) ctx.theme
ui-primitives/ Pure React atoms: icons, Button/Pill/Menu/Modal/Input, markdown family (component library)
ui-layout/ Shell three-column AppFrame; declares sidebar / conversation / details / conversation.empty ctx.layout
ui-sidebar/ Sidebar shell: Workspace/session rail, search, collapse; declares sidebar.workspaces (slot host)
ui-workspace/ Shared Workspace picker: browser region + hero picker over the same creation flow (fills sidebar.workspaces, conversation.hero.workspace)
ui-conversation/ Conversation domain: skeleton, chat view, input dock, per-tool row slots (slot host)
ui-trajectory/ Trajectory/Waterfall view tabs; the minimal pure-consumer plugin exemplar (fills conversation.view)
ui-command/ Command surface: session-keyed directory cache, / source, three-kind dispatch ctx.command
ui-slash/ Input trigger pipeline: / and @ detection, grouped candidate menu, source roster ctx.slash
ui-skill/ /-trigger skill reference source over the skill.list RPC (registers into ctx.slash)
ui-subagent/ @-trigger subagent reference source over the sessions snapshot (registers into ctx.slash)
ui-model/ Model selection: /model popupSelect + the composer model seat over ModelService ctx.models
ui-question/ Web ask_user_question: host half mounts the tool, browser half fills the composer seat (fills conversation.composer)
ui-settings/ Settings shell: trigger chrome + modal panel; declares the settings.* slots (slot host)
ui-settings-general/ Settings ownerless copy: chrome content + General section skeleton (fills settings.*)
ui-models/ Models settings nav entry (content column lands in a later phase) (fills settings.section)

Feature UI composes only through the slot system (ctx.slots.register) — the slot system standard is the definitive model; the web client architecture note owns the loading chain and object layer.
