FRE-603: Add Presence & Visibility Layer UI components
- CollaboratorList: Display connected users with presence state - RemoteCursorOverlay: Render remote cursors in editor - EditingIndicator: Show active editors and their context - Component index for clean imports - Tests for CollaboratorList Architecture: - Polling-based presence updates (100ms for cursors, 500ms for editors) - Color-coded user indicators - Line:column cursor positioning - Selection highlighting with transparency Files: - src/components/collaboration/collaborator-list.tsx - src/components/collaboration/remote-cursor-overlay.tsx - src/components/collaboration/editing-indicator.tsx - src/components/collaboration/index.ts - src/components/collaboration/collaborator-list.test.tsx Co-Authored-By: Paperclip <noreply@paperclip.ing>
