feat: implement core VFS and Knowledge Layer methods

- Add setUser/getCurrentUser for collaboration tracking
- Add getAllTodos to recursively collect todos
- Add getProjectStats for project statistics
- Add findByConcept to search files by concept
- Add getTimeline for temporal event views
- Add getCollaborationHistory to track edits by user
- Add exportToMarkdown for directory export
- Add getEvents method to EventRecorder
- Update Knowledge Layer docs to remove unimplementable AI features
- Make all documented features real and production-ready

All core VFS and Knowledge Layer documentation now reflects 100% real,
working code. AI-powered features have been moved to future augmentations.
