Event system for Information Spaces.

This package provides event-driven architecture for space operations:
- SpaceEvent: Event dataclass with type, payload, timestamp
- SpaceEventType: Enum of all event types
- EventBus: In-process publish/subscribe for space events
- Event factory functions for common events

Events emitted:
- Space lifecycle: SPACE_CREATED, SPACE_UPDATED, SPACE_DELETED, SPACE_ACTIVATED, SPACE_ARCHIVED
- Document: DOCUMENT_ADDED, DOCUMENT_UPDATED, DOCUMENT_REMOVED, DOCUMENT_MOVED, DOCUMENT_CONTENT_CHANGED
- Variable: VARIABLE_SET, VARIABLE_DELETED
- Reference: REFERENCE_ADDED, REFERENCE_CLEARED
- Rendering: RENDER_STARTED, RENDER_COMPLETED, RENDER_FAILED
- Sync: SYNC_STARTED, SYNC_COMPLETED, SYNC_CONFLICT
- Cache: CACHE_INVALIDATED
