- Adds experimental ClickHouse storage support (factory, writer, event attributes, complex attribute column) and fixes the enabletracing parameter for Jaeger v2 queries.
- Refactors numerous UI components from class to functional components, updates to the modern JSX transform, replaces react‑window, and resolves UI bugs (flaky test, top‑bar tab order, auto‑expanding logs).
- Moves ClickHouse queries to embedded SQL files and adopts maps.copy for cleaner map handling.
