* fix(models_dev): map meta-ai provider to models.dev 'meta' id
Muse Spark models (muse-spark-1.1/1.2/-contributor) are served via the Meta
Model API and reverse-map from api.meta.ai to the Hermes provider id 'meta-ai'.
models.dev keys the same models under the provider id 'meta'.
lookup_models_dev_context() / _get_provider_models() resolve the models.dev id
strictly via PROVIDER_TO_MODELS_DEV.get(provider) (no raw-id fallback, unlike
get_model_info()), so an unmapped 'meta-ai' missed entirely and context fell
back to the generic 256K default instead of the true ~1M window. Add the
meta-ai->meta mapping (plus a defensive meta->meta) so context and pricing
resolve from models.dev: 1.1=1,000,000; 1.2 & -contributor=1,048,576.
