Implement X thread context retrieval with proper chronological ordering
- Add conversation_id field to mention search parameters
- Implement get_thread_context() to fetch complete conversation threads
- Add thread_to_yaml_string() for clean AI-readable thread format
- Fetch original tweets directly when missing from conversation search
- Sort tweets chronologically (oldest first) for proper context
- Add 'python x.py thread' command to test thread context retrieval
- Clean YAML output with only text, created_at, and author fields
Thread context now shows complete conversation history in correct order:
1. Original mention → 2. void's reply → 3. Follow-up responses
