- Update "What is AI-Trader?" section to "What is AI-Trader-Server?"
- Update all repository URLs from github.com/Xe138/AI-Trader to github.com/Xe138/AI-Trader-Server
- Update Docker image references from ghcr.io/xe138/ai-trader to ghcr.io/xe138/ai-trader-server
- Update Python client class name from AITraderClient to AITraderServerClient
- Update docker exec container name from ai-trader to ai-trader-server
- Add fork acknowledgment section before License, crediting HKUDS/AI-Trader
