feat(dsh): adapt to DSH 0.1.5-alpha.1

Move the plugin onto the DSH 0.1.5-alpha.1 baseline (peer floor ^0.1.5-alpha.1, CI pinned to the alpha dist-tag) and fix the two host contract changes that alpha line introduced. Baseline: - all @deepseek-ai/dsh-* peer/dev deps -> 0.1.5-alpha.1; optional peer @deepseek-ai/dsh-client-ui-sidebar-right (declared, unused until the native-surface phase); devDep @deepseek-ai/dsh-agent-loop (inbox fold) - dsh.plugin.json engines >=0.1.5-alpha.1; version 0.19.0-alpha.0; SIDEBAR_SERVICE_VERSION follows Live assistant stream (assistant/chunk is gone): - 0.1.5 publishes in-flight model deltas as process-local agent/assistant-stream frames instead of durable assistant/chunk events and embeds the settled stream in assistant/message / assistant/attempt. src/assistant-live.ts folds the frames into a bounded per-session buffer; sidechat.events serves the current attempt as `live` rows (replaced every poll, never a delta) and the transcript renders them; the inherited in-progress snapshot reads message content / attempt stream / live frames. Cold session reads (persistence.inspect is gone): - 0.1.5 reads a stored session through an explicit read handle (open(id,'read') -> handle.read() -> close()). src/session-store.ts owns that protocol; every cold read (sidechat transcript, cold-resume preset, session.cwd, changes replay) goes through it. Dead code and docs: - drop the remote.session.openWorkspacePath interception: 0.1.5's chat opens files through ctx.sidebarRight.openResource instead, so the wrapper had no caller and would hijack the host's "open in app" gesture; the interceptOpenPath pref, its settings row and its locale keys go with it - AGENTS.md §3 + external-plugin-guide.md describe the new baseline - vitest setup bridges Node's localStorage accessor to jsdom's store (the pre-existing 26 failures on Node >= 22) - desktop-layout e2e seeds through host RPC and types into the Lexical composer (0.1.5 replaced the textarea) instead of driving the directory picker Verified: pnpm typecheck / lint / build / test (124 files, 1327 tests) / check:consumer-types, plus pnpm test:mount against a real @deepseek-ai/dsh@0.1.5-alpha.1 host (18/18).

-/**
- * Interception of the chat's file-open funnel (DSH 0.1.2-alpha hosts).
- *
- * The alpha funnel is the Typert remote namespace `remote.session`: every
- * chat-side file open (tool-row path links, the produced-files row, prose
- * file mentions, inline-code paths) funnels through ChatView's injected
- * `openFile`, which calls `ctx.remote.session.openWorkspacePath({ path })`
- * with the path ALREADY resolved against the session cwd (verified against
- * the DSH source: `packages/client/ui-chat/src/client/apply.ts` is the only
- * production caller). The host side (`api/session-controller`) hands the
- * path to the OS's default application (`openNativePath` → xdg-open on
- * Linux). The pre-alpha funnel `ctx.workspaces.openPath` is gone — the
- * alpha `IWorkspaces` has no openPath at all.
- *
- * `remote.session` is a cordis service (the gateway client's
- * RemoteNamespaceService, key `remote.session`) whose methods are installed
- * as ACCESSOR properties (`Object.defineProperty(service, method, {
- * configurable: true, get })`) — the getter reads the method table at
- * ACCESS time and returns the invocation closure. A plain assignment would
- * not stick (no setter), so the wrapper shadows the method with a data
- * property and restores the captured accessor descriptor on dispose.
- *
- * The namespace service appears asynchronously (the session-controller
- * contribution mounts after the connection is up) and is disposed/recreated
- * on contribution remounts; the caller therefore enters through
- * `ctx.inject(['remote.session'], …)`, which re-fires on every remount.
- *
- * The wrapper is dependency-free by design (no React / ui-primitives), so
- * the takeover logic is unit-testable and the file stays importable from
- * the test runtime.
