- Added `/assistent/client-event` and `/assistent/client-events` endpoints for tracking UI interactions and retrieving event history.
- Updated Debug API documentation to reflect new endpoints and their functionalities.
- Enhanced Assistent session handling with improved client prediction logic and diagnostics.

 Ответ chat: `ok`, `reply`, `trace` (`timings_ms`, `patch`, `exact_merge`, `compact_context`, `system_chars` / `system_layers`, `skills`, `hops`, `gaps`, `errors`/`warnings`/`hints`). Sqlite SaveChat fail — soft error, если текст ответа есть.
