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

- Sanitization of orphaned parentId references on state load
History Fixes:
- pushToHistory now syncs timeline with graphStore before snapshot
- Prevents missing groups/nodes in history states
- Ensures undo/redo correctly restores all graph elements
- Atomic state updates to avoid React Flow processing stale state
Storage & Persistence:
- Groups saved in timeline states and document structure
- Safe JSON serialization to prevent prototype pollution
- Cleanup utilities for removing __proto__ from localStorage

Implements a comprehensive label system and completely redesigns all
filtering (labels, actor types, relation types) to use intuitive positive
filtering where empty selection shows all items.
Label System Features:
- Create, edit, delete labels with names, colors, and scope (actors/relations/both)
- Inline editing with click-to-edit UI for quick modifications
- Quick-add label forms in config modals
- Autocomplete label selector with inline label creation
- Label badges rendered on nodes and edges (no overflow limits)
- Full undo/redo support for label operations
- Label validation and cleanup when labels are deleted
- Labels stored per-document in workspace system
Filter System Redesign:
- Changed from negative to positive filtering for all filter types
- Empty selection = show all items (intuitive default)
- Selected items = show only those items (positive filter)
- Consistent behavior across actor types, relation types, and labels
- Clear visual feedback with selection counts and helper text
- Auto-zoom viewport adjustment works for all filter types including labels
Label Cleanup & Validation:
- When label deleted, automatically removed from all nodes/edges across all timeline states
- Label references validated during node/edge updates
- Unknown label IDs filtered out to maintain data integrity
UI Improvements:
- All labels rendered without overflow limits (removed +N more indicators)
- Filter checkboxes start unchecked (select to filter, not hide)
- Helper text explains current filter state
- Selection counts displayed in filter section headers

Implements configurable shape variants for actor nodes, allowing visual
differentiation of node types beyond just color.
Features:
- Five shape options: rectangle, circle, rounded rectangle, ellipse, pill
- All shapes use pure CSS (border-radius) for consistent behavior
- Auto-grow with content
- Perfect shadow and selection/highlight effects
- Proper React Flow handle alignment
- Shape selector UI with visual previews
- Migration logic for existing documents (defaults to rectangle)
Shape characteristics:
- Rectangle: Standard, general purpose
- Circle: Round, for people and concepts
- Rounded Rectangle: Soft edges, friendly appearance
- Ellipse: Oval/horizontal, for processes and stages
- Pill: Capsule, compact for tags and labels
Technical approach:
- Uses border-radius for all shapes (no clip-path)
- Ensures boxShadow follows shape contours properly
- Each shape component maintains consistent props interface
- NodeShapeRenderer routes to appropriate shape component

Fixed critical bug where importing a document would lose all timeline
states except the current one. Also cleaned up unused legacy persistence
functions.
Changes:
- Import now preserves complete document structure with all timeline states
- Export already worked correctly, serializing all timeline states
- Updated fileIO to return full ConstellationDocument instead of just graph
- Removed unused legacy functions: hasSavedState, getLastSavedTimestamp, clearSavedState
- Removed unused graphStore export/import (replaced by workspace-level system)
- Updated type definitions to reflect removed functions
The import process now correctly:
1. Accepts full ConstellationDocument from imported JSON
2. Preserves all timeline states and relationships
3. Loads complete timeline into timelineStore
4. Maintains document title and metadata

- Separate marker definitions for start/end to ensure correct orientation
**Property Panel Controls:**
- MUI ToggleButtonGroup for selecting directionality
- Visual connection indicator with directional symbols
- Reverse direction button (swaps source/target, only for directed edges)
- Live updates with 500ms debounce
**Edge Type Configuration:**
- Default directionality selector in edge type form
- Dropdown with helpful descriptions (→, ↔, —)
- Applied to both create and edit workflows
**Edge Creation:**
- New edges inherit defaultDirectionality from edge type config
- Falls back to 'directed' for backwards compatibility
**Reverse Direction:**
- Swaps source/target and sourceHandle/targetHandle
- Maintains edge ID and selection state
- Tracked in undo/redo history
Includes comprehensive UX specification document with wireframes,
interaction patterns, accessibility guidelines, and implementation phases.
