[Enchancement] Improvement proposals for llama

I wold like to propose some improvement ideas with could help to make LLama better:

1. add as default a working list of MCP repositories instead leaving it empty
2. add possibility to use Skills
3. make LLama extendable
4. create an extensive documenttion of LLama, giving very much focus on configuration releated matters
5. add support for internationalization
6. make the configuration possibilities more advanced
