feat: Enhance log parser to support Cursor CLI events

- Added functions to detect and normalize Cursor stream events, including tool calls and system messages.
- Updated `parseLogLine` to handle Cursor events and integrate them into the log entry structure.
- Marked completion of the log parser integration phase in the project plan.
