Refactor and restructure core components

- Removed obsolete files: `hanle_multi.go`, `logger.go`, `handle_com.go`, `handle_list.go`, `server.go`, and `utils.go` from the `general_server` and `sv1` packages.
- Introduced new implementations for the `GeneralServer` and `HandlerV1` in the `core` package, enhancing the overall architecture.
- Updated the `go.mod` and `go.sum` files to include new dependencies.
- Added a new configuration structure in `config.yaml` and `config.go` for better management of application settings.
- Implemented a Lua command handling mechanism in `handle_com.go` and `handle_list.go` for improved command execution.
- Enhanced logging capabilities with a new logger setup in `logger.go`.
- Added a new Lua script `http.lua` for handling HTTP requests.
