Applies default per-call settings to every model invocation. Explicitly provided params override defaults; provider option maps are merged.
Implemented via LanguageModelMiddleware.transformParams (the params-only seam), so the defaults apply uniformly to both generate and stream — matching v6's defaultSettingsMiddleware. Use cases:
