- **Enhanced Logging**: More detailed logging for debugging and troubleshooting

This release significantly improves Azure OpenAI compatibility, especially for the latest reasoning models (o1, o3 series), while providing a much better user experience for model management and configuration.

🐛 Bug Fixes:
• Fixed newline formatting issue with Ollama translations when typing in the "Original Text" field
• Improved Ollama response parsing to properly handle escaped newlines
• Enhanced text formatting consistency across all translation providers

🔧 Technical Improvements:
• Updated Ollama prompt instructions to preserve line breaks and formatting
• Added defensive programming for various newline escape formats (\n, /n, \r\n, \r)
• Improved translation response processing for better text formatting

This is a minor bugfix release that resolves the issue where Ollama would return literal "/n" instead of actual newlines when translating multi-paragraph text entered manually in the input field.

🚀 New Features:
• Ollama Support: Added complete support for Ollama local AI models for offline translation
• Provider Architecture: Refactored translation system with modular provider design
• Local Translation: Run translations completely offline with privacy-focused local models

🎯 Improvements:
• Provider UI: Beautiful new provider selection grid with professional icons
• Settings Redesign: Replaced dropdown with intuitive card-based provider selection
• Better Organization: Split translation code into separate provider modules
• Enhanced Config: Added ollama_url configuration with automatic defaults

🔧 Technical:
• Added ollama-rs crate integration for robust Ollama communication
• Improved error handling across all translation providers
• Enhanced validation system for all API endpoints including Ollama server connectivity

🐛 Bug Fixes:
• Azure API compatibility: Fixed "error sending request" issue by properly handling different Azure endpoint formats
• URL parsing: Robust parsing of Azure URLs with proper error handling
• Model flexibility: Removed restrictions that prevented using custom/newer models

🎯 Key Improvements:
• Better Azure Support: Now handles both Cognitive Services and Models API endpoints seamlessly
• User Experience: Real-time feedback when pasting Azure URLs with automatic extraction
• Visual Design: Professional header with larger SVG logo and better typography
• Flexibility: Removed hardcoded model restrictions, allowing any model name
• Error Handling: Comprehensive validation with clear error messages
• Icon update: Icon has been updated
