feat(tests): implement test runner functionality with API integration

- Added Test Runner Service to manage test execution processes for worktrees.
- Introduced endpoints for starting and stopping tests, and retrieving test logs.
- Created UI components for displaying test logs and managing test sessions.
- Integrated test runner events for real-time updates in the UI.
- Updated project settings to include configurable test commands.

This enhancement allows users to run tests directly from the UI, view logs in real-time, and manage test sessions effectively.
