Release version 0.21.0

• feat(workspace): A redesigned four-column desktop workspace. Sidebar, conversation, file, and aux panel each get a full-height column with its own top bar; tabs move into the title bar, and new conversation and file detail headers carry quick actions.
• feat(aux-panel): A new Session Details tab. The right panel now shows the active conversation's metadata and live token usage, and hosts the Git branch and command selectors moved out of the title bar.
• feat(appearance): Custom workspace background image with frosted surfaces. Set an image in Appearance settings and tune its blur and opacity; chrome surfaces turn to frosted glass while editors and overlays go transparent.
• feat(appearance): Accent themes now color the whole interface. Muted panels, the sidebar, borders, the light canvas, and the editor background all carry the theme's hue instead of staying gray.
• feat(file-tree): Drag tree entries to move them, or into the composer to reference them. Drop a file or folder onto another folder to move it, or into the chat box to insert a reference.
• feat(workspace): Custom folder aliases. Set an alias from a folder's context menu; the sidebar and header show "alias [ name ]".
• feat(grok): Grok's built-in ask_user_question is now interactive. Its questions render as codeg's question card and your answer goes back to Grok, instead of a dead, unanswerable card.
• fix(sync): A reply that finishes on another device now appears for everyone watching. It syncs into your open conversation instead of showing up only after a reload.
• fix(chat): A clearer composer border and selected quick-action tab. The resting border stays visible in every theme and over a background image, and the active tab now stands out.
• chore(agents): Bundled agents refreshed. Cline 3.0.44, CodeBuddy Code 2.124.0, Kimi Code 0.27.0, and Grok 0.2.103.
