feat: UI design system - sidebar layout, workspace system, and shell redesign (#77)

* feat: add workspace system and sidebar layout (UI design system Phase A+B) Backend: Workspace model, migration (036), schemas, CRUD API endpoints. Adds workspace_id to trees and categories, seeds 4 default workspaces per account, auto-assigns existing trees by tree_type. Frontend: Complete AppLayout rewrite from top-nav to CSS Grid shell with persistent sidebar + topbar. New components: WorkspaceSwitcher, NavItem, CategoryList, TagCloud, TopBar, Sidebar. Dashboard components: QuickStats, FiltersBar, SectionGroup, TreeListItem, SessionsPanel. WorkspaceStore with localStorage persistence. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: add command palette search, dashboard rewrite, and shell height fixes (Phase C) - Add ⌘K command palette with debounced search across flows and sessions - Rewrite QuickStartPage as dashboard with stats, filters, sessions panel - Fix h-[calc(100vh-4rem)] → h-full across all pages for CSS Grid shell - Add active session count badge to sidebar Sessions nav item Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: add sidebar collapse, category/tag filtering, and workspace CRUD (Phase D) - Sidebar collapse/expand toggle with icon-only rail mode (persisted) - Sidebar category/tag clicks navigate to /trees with URL params - TreeLibraryPage syncs filters from URL search params bidirectionally - Workspace create modal with icon picker and auto-slug generation - TopBar logo adapts to collapsed sidebar state Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: add Quick Launch modal with actions and recent flows - Zap button opens Quick Launch with create/navigate shortcuts - Shows recent flows for quick session start - Keyboard navigation support (arrows + enter) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: add activity notifications panel with session feed - Bell icon shows dot indicator for recent activity - Dropdown panel shows recent sessions with status icons - Links to session detail and sessions list page Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: remove workspace system, add pinned flows and label renames Replace workspace system with pinned flows API (pin/unpin/list/reorder). Rename user-facing labels: Tree→Flow, Procedure→Project. Add sidebar nav sub-items for flow type filtering. Remove 11 workspace files, add migrations 037-038, clean all workspace references. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: collapsed sidebar layout scaling and toggle button size Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: migrate auth pages to new design system Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: migrate TreeLibraryPage to new design system Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: migrate session pages to new design system Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: migrate TreeEditorPage to new design system Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: migrate TreeNavigationPage to new design system Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: migrate session sharing components to new design system Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * chore: remove workspace dropdown animation (dead code) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: migrate common components to new design system Migrate 15 components from monochrome glass-card design to purple gradient accent design system tokens (bg-card, border-border, text-foreground, bg-gradient-brand, etc.) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: migrate procedural and step library components to new design system Migrate 10 components from monochrome glass-card design to purple gradient accent design system tokens. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: migrate admin pages and components to new design system Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: migrate remaining pages to new design system Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: migrate remaining components to new design system Migrates 38 files: tree-editor forms, session modals, step library, common components, library views, tree preview, and misc UI to use design tokens (bg-card, border-border, text-foreground, bg-accent, bg-gradient-brand) replacing old monochrome patterns. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: keep brand text visible on sidebar collapse, hide sub-items until hover - TopBar: always show "ResolutionFlow" text regardless of sidebar state - NavItem: sub-items (Troubleshooting, Projects) hidden by default, revealed on hover or when a child route is active Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
