Add Terminal Trainer - Issue #381

[konard]

Summary

• Added terminal trainer functionality to the GPTutor application
• Implemented TERMINAL_TRAINING mode type for command line learning
• Created Linux terminal simulator with interactive training interface
• Added bash syntax highlighting support for the code editor

Changes Made

• ModeType: Added TERMINAL_TRAINING = "TERMINAL TRAINING" to support the new trainer mode
• Languages: Added Terminal = "bash" for proper syntax highlighting in both Ace and Monaco editors
• Trainer Configuration: Created terminal-specific prompt that simulates a Linux terminal environment
• Integration: Seamlessly integrated with existing trainer system - appears automatically in home screen
• Initial Example: Set up with ls -la command as starting example

How it Works

1. Users can access the terminal trainer from the main screen alongside other trainers (JS, Python, Go)
2. The trainer uses a Linux terminal simulation prompt that responds to commands with realistic terminal output
3. Code editor provides bash syntax highlighting for better command visibility
4. Follows the same workflow as other trainers: Editor → Chat interface for interactive learning

Test Plan

• Added new mode type and language enum
• Created terminal trainer configuration with appropriate prompt
• Integrated into existing trainer system
• Verified syntax highlighting support (bash language supported by both editors)
• Confirmed automatic integration with home screen via existing trainer logic

The implementation follows the existing pattern used by other trainers (JS, Python, Go) and integrates seamlessly without requiring additional UI changes.
