Function loadLLMRuntime

cmd/opencodereview/shared.go:173–217

loadLLMRuntime loads tool defs from toolConfigPath, reads the app config from the user's default config path (applying the configured language to tpl — defaulting when the config file is absent), resolves the LLM endpoint (honoring resolveOpts), and returns the runtime bundle. tpl is mutated in plac

// returns the runtime bundle. tpl is mutated in place.
