feat: add CLI Command Node and Prompt Node components for orchestrator

- Implemented CliCommandNode component for executing CLI tools with AI models.
- Implemented PromptNode component for constructing AI prompts with context.
- Added styling for mode and tool badges in both components.
- Enhanced user experience with command and argument previews, execution status, and error handling.

test: add comprehensive tests for ask_question tool

- Created direct test for ask_question tool execution.
- Developed end-to-end tests to validate ask_question tool integration with WebSocket and A2UI surfaces.
- Implemented simple and integrated WebSocket tests to ensure proper message handling and surface reception.
- Added tool registration test to verify ask_question tool is correctly registered.

chore: add WebSocket listener and simulation tests

- Added WebSocket listener for A2UI surfaces to facilitate testing.
- Implemented frontend simulation test to validate complete flow from backend to frontend.
- Created various test scripts to ensure robust testing of ask_question tool functionality.
