Fix lint issues and regenerate CLI docs

- Rename pkg/llm types to drop LLM prefix (revive stutter: LLMConfig →
  Config, LLMOIDCConfig → OIDCConfig, etc.)
- Fix unused cmd parameter in config show RunE (revive)
- Use FormatJSON constant instead of raw "json" string (goconst)
- Fix gci import ordering in pkg/config/config.go
- Regenerate docs/cli/ for the new thv llm command group
