Multi-Frontend SSE Event Architecture

Catalyst now sends all orchestration events through a standardized envelope format with filtering support. Connect multiple frontends or tools to the same session using SSE query params like ?filter=session-update,metrics-update or ?session=abc123 to get only the events you need. The new typed event system supports session updates, metrics changes, and annotation events with automatic envelope wrapping for consistent downstream processing.
