feat: add agent selector to UI and support direct agent assignment

- Added an agent selector (Auto, Claude, Gemini) to the Start Next Task button.
- Updated the backend to pass query parameters as environment variables to scripts.
- Modified the executor pool to skip classification when a specific agent is requested.
- Added --agent flag to claudomator start command.
- Updated tests to cover the new functionality.
