Refactor to use LuaJIT and improve performance

Integrate LuaJIT as an optional runtime for better performance, with a fallback to standard Lua 5.4. Update Dockerfile to install LuaJIT and create a wrapper script for execution. Enhance network module with socket fallback support and update README to reflect these changes and configuration options.
