OrChat v1.3.1

What's New in OrChat 1.3.1

Auto-Update System: Added automatic update checking at startup - OrChat now checks for new versions via pip and prompts users to update, making it easier to stay current with new releases. (#18)
Multi-line Input Support: Implemented multi-line message support using Esc+Enter key combination, allowing users to compose longer, multi-paragraph messages with visual feedback. (#15)
Smart File Picker: Replaced /attach and /upload commands with a modern # file picker that provides intelligent auto-completion, file browsing, and can be used anywhere in your message (e.g., analyze #config.py and tell me what it does).

Interactive File Browser: The new file picker displays files with appropriate icons (🐍 Python, 📄 Text, 🖼️ Images), file sizes, and directory navigation with a clean popup interface.
Enhanced Input Experience: Multi-line mode shows [Multi-line] status indicator and provides seamless toggling between single and multi-line input modes.
Improved File Attachment Flow: Natural language file attachment - users can now write "examine #test.py and check for errors please" instead of separate commands.

Accurate Token Counting: Fixed token counting inaccuracies by using OpenRouter API's actual usage data instead of local tiktoken estimates, providing precise counts for attachments, system prompts, and thinking content. (#13)
Code Refactoring: Comprehensive optimization of main.py reduced codebase by 264 lines (8.7% improvement) while maintaining full functionality and improving maintainability.
Enhanced Security: Added robust file validation, improved error handling, and implemented better configuration management with type hints throughout.

Free Model Pricing: Fixed cost calculation bug where free models (ending with :free) were incorrectly showing monetary costs instead of displaying "FREE".
Command Cleanup: Removed non-functional /compress command that was causing "Unknown command" errors.
File Picker Context: Fixed issue where typing additional text after filename (e.g., #file.py carefully) wasn't working correctly - now properly separates filename from additional message context.
Multi-position File Picker: File picker now works anywhere in your message, not just at the beginning of prompts.

Optimized Imports: Reorganized and streamlined imports for faster startup times.
Improved Memory Usage: Enhanced class structures and reduced code duplication for better resource utilization.
Better Error Handling: Added comprehensive error handling with graceful fallbacks throughout the application.

Special thanks to @e-ndorfin for reporting the token counting bug that led to the API usage integration improvement.
