Jan-Henrik Bruhn d775cb8863 refactor: migrate undo/redo from per-state to per-document level ... 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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>		2025-10-11 22:38:23 +02:00
