Description

New Components & Modules

• New ProjectPageSidebar (1,164 lines) — collapsible left sidebar rail for project-level navigation (workspace tabs, task list with lifecycle status indicators, help/support menu)
• New RichChatInput (430 lines) — rich text input with inline URL and #skill token highlighting
• New UserMessageRichContent — renders rich content segments in user message cards
• New taskLifecycleUi.ts utility — centralizes task lifecycle state derivation (bottom-box state, shelf tone) shared between sidebar and chat
• New useInitialChatPanelLayout hook — handles initial resizable panel sizing on mount

Layout & Navigation Overhaul

• Home.tsx heavily refactored — integrates ProjectPageSidebar, replaces inline connection-status/tab logic with sidebar-driven navigation
• TopBar gains browser-style back/forward navigation (useStackNavigationBounds), removes export-log and folder icon; adds share/sparkles icons
• WorkspaceMenu renamed to WorkSpaceMenu (casing change)
• Sidebar-driven workspace tab switching replaces the old MenuToggleGroup in-page tabs
• BottomBar simplified, workspace components (BrowserAgentWorkspace, TerminalAgentWorkspace) receive minor layout adjustments

State Management

• pageTabStore now uses zustand/persist, adds: projectSidebarCollapsed, scrollToQueryId, customAgentFolderPathByProjectId, workspaceChatFocusRequestId
• Removed hardcoded hasTriggers mock — now derived from actual trigger data

ChatBox Refactoring

• Removed model-config polling logic (cloud/local/custom key checks) — hasModel defaults to true
• Removed per-project token aggregation (projectTotalTokens, getChatStoreTotalTokens)
• Deleted ExpandedInputBox.tsx (239 lines removed), replaced by RichChatInput
• Dynamic scroll bottom inset via ResizeObserver on the bottom-box overlay
• workspaceChatFocusRequestId auto-focuses chat input when sidebar triggers it

UI Component Updates

• button.tsx rewritten — new layout axis (text | icon-only), compound variants per size, textWeight and radius props, proper icon-only square sizing
• Multiple UI primitives (dialog, dropdown-menu, input, textarea, carousel, command, resizable, sidebar) receive styling/structure tweaks

i18n

• New keys across all 12 locales for sidebar labels, trigger sort options, and setting strings
