Implements comprehensive group minimize/maximize functionality and migrates
to React Flow v12 (@xyflow/react) with improved edge routing.
## Group Minimize/Maximize Features:
- Minimized groups render as compact 220×80px solid rectangles
- Original dimensions preserved in metadata and restored on maximize
- Child actors hidden (not filtered) to prevent React Flow state issues
- Solid color backgrounds (transparency removed for minimized state)
- Internal edges filtered out when group is minimized
- Dimension sync before minimize ensures correct size on maximize
## Floating Edges:
- Dynamic edge routing for connections to/from minimized groups
- Edges connect to closest point on minimized group border
- Regular actors maintain fixed handle connections
- Smooth transitions when toggling group state
## React Flow v12 Migration:
- Updated package from 'reactflow' to '@xyflow/react'
- Changed imports to named imports (ReactFlow is now named)
- Updated CSS imports to '@xyflow/react/dist/style.css'
- Fixed NodeProps/EdgeProps to use full Node/Edge types
- Added Record<string, unknown> to data interfaces for v12 compatibility
- Replaced useStore(state => state.connectionNodeId) with useConnection()
- Updated nodeInternals to nodeLookup (renamed in v12)
- Fixed event handler types for v12 API changes
## Edge Label Improvements:
- Added explicit z-index (1000) to edge labels via EdgeLabelRenderer
- Labels now properly render above edge paths
## Type Safety & Code Quality:
- Removed all 'any' type assertions in useDocumentHistory
- Fixed missing React Hook dependencies
- Fixed unused variable warnings
- All ESLint checks passing (0 errors, 0 warnings)
- TypeScript compilation clean
## Bug Fixes:
- Group drag positions now properly persisted to store
- Minimized group styling (removed dotted border, padding)
- Node visibility using 'hidden' property instead of array filtering
- Dimension sync prevents actors from disappearing on maximize

Replaces Material-UI components in Timeline dialogs with custom Tailwind
CSS styling to match the application's standard dialog design.
Changes:
- RenameStateDialog: Replaced MUI Dialog, TextField, and Button components
with custom styled elements matching ConfirmDialog/InputDialog pattern
- CreateStateDialog: Converted all MUI form components (TextField, Checkbox,
Button) to native HTML elements with Tailwind styling
- Added consistent visual design with large icons, gray backgrounds, and
proper spacing
- Improved keyboard handling (Enter/Escape) with proper event listeners
- Enhanced focus management with auto-select on input fields
- Maintained all existing functionality while improving UI consistency
Both dialogs now feature:
- Icon-based visual hierarchy with 48px icons
- Consistent button styling (gray cancel, blue confirm)
- Proper disabled states and hover effects
- Gray-50 background on action button areas
- Backdrop click to close

Removes the upper toolbar and consolidates undo/redo controls into the
Edit menu for a cleaner interface with more screen space.
Changes:
- Move undo/redo buttons from Toolbar to Edit menu with descriptions
- Remove Toolbar component from App layout
- Implement closeAllMenus event system for coordinated menu management
- Add event listeners to close menus when clicking on graph/timeline canvas
- Add cross-menu closing: context menus close menu bar and vice versa
- Fix React warning by deferring event dispatch with setTimeout
Benefits:
- Cleaner UI with more vertical space for graph editor
- Unified menu system prevents multiple menus open simultaneously
- Context menus and menu bar dropdowns coordinate properly
- Consistent UX: clicking anywhere closes open menus

- Increase collapsed bottom panel height from 40px to 48px for better proportions
- Show current state indicator in bottom panel even when collapsed
- Remove unnecessary and broken close button from right panel header

Implements a comprehensive timeline system that enables documents to contain
multiple constellation states with branching timelines. This allows users to
create different versions of their analysis for temporal evolution, alternative
scenarios, or what-if analysis.
Core Features:
- Timeline store managing multiple states per document with branching structure
- Visual timeline panel with React Flow-based state graph visualization
- State management: create, switch, rename, duplicate (parallel/series), delete
- Per-state undo/redo history (max 50 actions per state)
- Context menu for timeline node operations
- Collapsible timeline panel (always visible, moved toolbar to panel header)
Architecture Changes:
- Document structure: removed top-level graph field, states now only in timeline
- Global types: nodeTypes and edgeTypes are now global per document, not per state
- State graphs: only contain nodes and edges, types inherited from document
- Persistence: full timeline serialization/deserialization with all states
- History system: converted from document-level to per-state independent stacks
Timeline Components:
- TimelineView: main timeline visualization with state nodes and edges
- BottomPanel: collapsible container with timeline controls in header
- StateNode: custom node component showing state info and active indicator
- CreateStateDialog: dialog for creating new timeline states
- RenameStateDialog: dialog for renaming existing states
- Context menu: right-click operations (rename, duplicate parallel/series, delete)
Document Management:
- Documents always have timeline (initialized with root state on creation)
- Timeline persisted with document in localStorage
- Export/import includes complete timeline with all states
- Migration support for legacy single-state documents
Store Updates:
- timelineStore: manages timelines, states, and timeline operations
- historyStore: per-state history with independent undo/redo stacks
- workspaceStore: saves/loads timeline data, handles global types
- panelStore: added timeline panel visibility state
- useActiveDocument: syncs timeline state with graph editor
Context Menu Improvements:
- Smart viewport edge detection to prevent overflow
- Click-outside detection for React Flow panes
- Consistent styling across application

- src/types/timeline.ts - Timeline type definitions
- src/stores/timelineStore.ts - Timeline state management
