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

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.
