feat(agent-runner, session-management): enhance markdown formatting and session hotkey functionality

- Added a React library for proper markdown formatting in the Agent Runner, improving the display of session messages.
- Changed the hotkey for creating a new session from "W" to "N" to ensure consistency across new feature buttons.
- Updated the feature list to include new entries for these enhancements, along with a detailed implementation roadmap in the project specification.

These changes improve user experience by enhancing message readability and streamlining session management.
