Améliorations UI

Whale tray launcher for DeepSeek Harness: a Windows system-tray app and a macOS menu-bar app that start/stop the dsh service, summon the Web UI, restart and top up — running independently of the dsh process, like a Steam launcher for dsh.

Four right-Sidebar panels for the dsh web client — an artifacts browser, long-term memory, a terminal and notes — paired two per tab with a draggable split, so two panes show all four at once. Ships the host half as well: nine memory_* tools, artifacts_list, the /memory command, the /api/artifacts/* and /api/terminal-notes/* routes. The terminal runs one bash command per line, with a 120-second deadline and a stop button. Requires dsh 0.1.5 or newer, which is where the right Sidebar replaced the old details column.

Adds customizable switch shortcut buttons to the left of the DSH Web GUI chat input for one-click slash-command insertion.

ChatGPT-style side chat for the DSH Web GUI: ask small questions about the current topic in a floating side panel, answered by an independent lightweight session over the official /api RPC — the main conversation is never touched. Streaming text, collapsible reasoning, tool chips, stop button, agent-preset selector, and an automatic context snapshot from the visible main chat.

Font switcher for DeepSeek Harness Web GUI: 99 UI fonts + 31 code fonts with CJK-Latin pairing.

Radial right-click menu on conversation turns in the DSH web GUI for forking a session from a chosen turn, interrupting generation, copying the working directory path or session ID, opening the working directory, and exporting session logs.

Select text in any Windows app to explain or translate it with the Harness agent, answered in a native always-on-top overlay.

Adds a one-click prompt optimization button to the DSH composer, with undo and an optional dedicated optimizer model.

Teaching board view: agent-generated self-contained HTML is projected into a sandboxed iframe as a board, annotated by hand (brush, four colours, eraser, undo), extended in place across several tool calls, and screenshotted back into the conversation as a real user message.

Session model selector with search: two-stage loose matching (normalised substring first, subsequence as fallback, so glm53 finds GLM-5.3 and ds finds DeepSeek), providers with recent successful calls pinned first, and a reasoning-effort pane that remembers each model's last explicitly chosen effort.

Replace the dsh-whale-widget mascot with your own image through a built-in cutout pipeline, plus a session-header restart button, a browser heartbeat, and an opt-in patch self-heal that is off by default.

Show the running DeepSeek Harness version and every mounted plugin's package version inside the dsh web UI.

Persistent, conversation-decoupled multi-shell terminal panel for DeepSeek Harness (DSH): real tmux TTYs, 11 model tools, draggable floating panel

终端面板：在当前工作区敲命令、看实时输出，多标签页、Tab 补全、Ctrl+C 中断。Terminal panel for DeepSeek Harness: run commands with streaming output, tabs, completion.

SoulFusion-style personalization: 9 response styles, custom instructions, persona cards, per-session switching, long-term memory with audit trails.

Adds Open workspace entries to the sidebar session-row menu and the session header actions slot, opening the session workspace folder in the system file manager.

Adds a right-click menu to DeepSeek Harness inside desktop shells that ship no context menu: cut, copy, paste and select all in the composer, copy and copy-as-plain-text on selected text elsewhere, and a search entry that opens the default browser with a configurable engine.

Floating translucent DeepSeek whale elf on the DSH page that opens a draggable, minimizable temporary chat window using the session model or a custom OpenAI-compatible endpoint, with real-time streaming.

MCP server management panel in Settings: add, edit, enable/disable and delete servers across user and workspace scopes with form or JSON editing, and auto-register discovered MCP tools as native conversation tools.

Five web UI tools in one plugin: a provider + model two-button selector with reasoning-level control, collapse/expand-all for sidebar workspace groups, a session tab listing the files the session changed (needs kernel 0.1.2-alpha.1+, silently absent on older kernels), a workspace badge next to the session title, and a settings page that toggles them.

The missing backend for the dsh-artifacts sidebar tab — serves the /report artifact index and the artifact bytes it renders.

LiveBench leaderboard for DSH — discovers the release the official site currently publishes, then reads its CSV and category JSON, and renders model rankings in an isolated same-origin iframe opened from a button beside the composer. Search, organization / open-weight / reasoning filters, per-category sorting, task-level detail, up to four models side by side, CSV export; refreshes every 60 s by default (configurable 30–3600) and caches only to the plugin's own .cache/rankings.json.

Adds a Long text button to the composer tool row: write or paste the body in an editor overlay, and on save it is written to <workspace>/.dsh-longtext/<timestamp>_<title>.md and an @ path reference to that file is appended to the composer, leaving the conversation free of the long text itself.
