I significantly expanded the envx CLI, transforming it into a comprehensive environment variable management system with database-backed versioning, tagging, and remote synchronization. I implemented new commands for configuration (init, test), variable management (set, del, load), history (history, tag), and remote operations (push, pull). I also updated docs/README-zh.md to reflect these changes and the new architecture.
