Refactors the type management system to properly follow the
Workspace→Document→Timeline→Graph hierarchy, where nodeTypes and
edgeTypes are owned by the document rather than being independent
state in graphStore.
Changes:
- Add type management actions to workspaceStore (document-level)
- Update workspaceStore.saveDocument to stop copying types from graphStore
- Modify useActiveDocument to only track node/edge changes for dirty state
- Update useGraphWithHistory to route type operations through workspaceStore
- Update useDocumentHistory to read/restore types from document
Architecture:
- Document: Source of truth for types (persistent storage)
- graphStore: Synchronized working memory (optimized for React Flow)
- useActiveDocument: Bridge that syncs document → graphStore
- Type mutations: Always go through workspaceStore, then sync to graphStore
This ensures proper data ownership while maintaining graphStore as a
performance optimization layer for the UI.

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

Refactors the history system to track complete document state instead of
individual timeline states, making timeline operations fully undoable.
BREAKING CHANGE: History is now per-document instead of per-timeline-state.
Existing undo/redo stacks will be cleared on first load with this change.
Changes:
- historyStore: Track complete document snapshots (timeline + all states + types)
- useDocumentHistory: Simplified to work with document-level operations
- timelineStore: All timeline operations now record history
- createState, switchToState, deleteState, updateState, duplicateState
- Fixed redo button bug (was mutating Zustand state directly)
New capabilities:
- Undo/redo timeline state creation
- Undo/redo timeline state deletion
- Undo/redo switching between timeline states
- Undo/redo renaming timeline states
- Unified history for all document operations
Technical improvements:
- Proper Zustand state management (no direct mutations)
- Document snapshots include entire timeline structure
- History methods accept currentSnapshot parameter
- Removed TypeScript 'any' types for better type safety

Removes duplicate confirmation dialogs when deleting documents.
Previously, users were asked twice: once by the UI component's custom
dialog and again by window.confirm in the store.
Changes:
- Remove window.confirm from workspaceStore deleteDocument function
- Add useConfirm hook to DocumentTabs component for delete action
- Consistent confirmation UX across DocumentManager and DocumentTabs
Both components now show the same styled confirmation dialog with
proper handling of unsaved changes warnings.

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
Files Added:
- src/types/timeline.ts - Timeline type definitions
- src/stores/timelineStore.ts - Timeline state management
- src/components/Timeline/TimelineView.tsx - Main timeline component
- src/components/Timeline/BottomPanel.tsx - Timeline panel container
- src/components/Timeline/StateNode.tsx - State node visualization
- src/components/Timeline/CreateStateDialog.tsx - State creation dialog
- src/components/Timeline/RenameStateDialog.tsx - State rename dialog
Files Removed:
- src/stores/persistence/middleware.ts - Obsolete persistence middleware
Documentation:
- Added comprehensive timeline feature documentation
- Implementation checklists and quick reference guides
- Temporal analysis concepts and UX guidelines

Implements toast notifications from UX_ANALYSIS.md to provide clear,
non-intrusive feedback for user actions.
Features:
- Toast store with Zustand for global state management
- Four toast variants: success, error, info, warning
- Auto-dismiss after configurable duration (default 4s)
- Max 3 visible toasts with FIFO queue
- Smart positioning that avoids right panel overlap
- Smooth slide-in/fade-out animations
Notifications added for:
- File operations (import/export success/errors)
- Document operations (create/delete/rename/duplicate)
- Workspace operations (import/export)
Toast container dynamically repositions based on right panel state
to ensure toasts never overlap with critical UI elements.

Fixes an issue where nodes from a previous document would persist when
creating a new document after closing all documents.
The problem occurred because:
1. When all documents were closed (activeDocumentId becomes null), the
graph store wasn't being cleared
2. When a new document was created, stale data from the old document
could contaminate the new document through race conditions
Changes:
- Clear nodes and edges from graph store when activeDocumentId is null
- Add safeguard to prevent saving stale graph data to newly created
documents before they've been fully loaded
- Maintain proper state tracking to prevent cross-document contamination

Added lastSyncedStateRef to track the graph state that was last loaded/synced
for each document. This prevents stale comparisons when switching between
documents by ensuring dirty checks only run against the correct document's
state.
Changes:
- Track last synced state (nodes, edges, nodeTypes, edgeTypes) per document
- Skip dirty check if graph state belongs to a different document
- Compare current graph state against last synced state instead of active document
- Update last synced state reference when loading or saving changes
