Enhance AI word generation and update to v0.1.1

Updated Wrdler to version 0.1.1 with significant enhancements to AI word generation, including intelligent word saving, retry mechanisms, and a 1000-word file size limit. Introduced dual generation modes using Hugging Face Space API and local transformers. Improved logging for better pipeline visibility. Updated documentation and added a new test for word file validation. Added new AI-generated word lists and a cooking-themed word list.

+2. **Validation Phase**: Check if file meets MIN_REQUIRED (25 words per length)
+3. **Retry Phase**: If insufficient, generate additional words (up to 3 attempts)
+4. **Save Phase**: Write only new words to topic-based file
+5. **Sort Phase**: Auto-sort by length then alphabetically
+6. **Limit Phase**: Stop adding if file reaches 1000 words
+
+### Error Handling
+- **HF Space API failure**: Graceful fallback to local model
+- **Model loading failure**: Try multiple models in priority order
+- **Device compatibility**: Retry pipeline without device parameter on error 422
+- **Insufficient words**: Automatic retry with targeted prompts
+- **File operations**: Detailed logging and error recovery
