feat(api): add llama.cpp support as local model provider

- Add llamacpp provider preset to provider-presets.ts
- Add base-llamacpp.settings.json configuration
- Update help-command.ts with ccs llamacpp documentation
- Update UI provider presets for dashboard parity

llama.cpp is a popular C++ inference engine for LLaMA models.
This complements existing Ollama support for local inference.

Usage: ccs llamacpp (requires llama.cpp server on port 8080)

Closes #690
