Refactor configuration and update handling:

- Modify .luarc.json to include global Lua scripts.
- Update Makefile to include LDFLAGS for versioning.
- Enhance node.go to implement version checking and update handling.
- Refactor Lua global variables in _globals.lua and echo.lua to use new structures.
- Remove deprecated http.lua and update config.yaml for TLS and update settings.
- Introduce new update.go for version management and update checking.
- Add tests for version comparison in update_test.go.
- Improve error handling in various server methods.
