v1.0.0-alpha.0

• Major updates: Refactored the codebase by moving hardware-specific (multi-chip) support into plugin repositories such as TransformerEngine-FL and vllm-plugin-FL. These plugins build on top of FlagOS, a unified open-source AI system software stack. We also re-initialized the Git commit history to reduce repository size.
• Compatibility (legacy users): If you are using or upgrading from a version earlier than v1.0.0-alpha.0, please use the main-legacy branch. It will continue to receive critical bug fixes and minor updates for a period of time.
