Design a professional web-based command-line interface (CLI) for code execution, drawing inspiration from the GraphQL Playground. Create an interface with the following features:
1. **Command Input Area:**
- Implement a text area where users can input commands, supporting multiline input for code snippets.
2. **Output Display:**
- Clearly present the output of executed code, distinguishing between standard and error outputs. Include options to collapse or expand the output for improved user experience.
3. **Language Selector:**
- Incorporate a dropdown or list allowing users to select the programming language for their code.
4. **Run Button:**
- Include a visually appealing button to execute the entered code. Optionally, implement keyboard shortcuts for quick execution.
5. **Clear/Reset Button:**
- Provide an intuitive button to clear the input area and reset the output display.
6. **Syntax Highlighting:**
- Apply syntax highlighting to the input code for enhanc | A shadcn/ui and v0 generation - v0
