// OpenAICompatibleProfile returns an in-memory Profile for an OpenAI-compatible
// chat-completions endpoint. A non-blank BaseProfileID permits its target
// fields to be inherited when the profile is selected or inspected.
//
// It does not register global state, maintain a model catalog, or resolve
// credentials. If APIKeyRequired is true, callers satisfy it with
// RunRequest.APIKey or an explicit request ExecutionTargetOverride.APIKeyEnv.
// Raw API keys do not belong in profiles.
//
// The function copies the ExtraParams map itself but does not recursively copy
// nested values. Validation and a deep copy occur when NewEngine applies a
// WithProfiles option containing the returned Profile.
