Add amazon.nova-premier-v1:0 to amazon-bedrock provider

Summary

amazon.nova-premier-v1:0 is missing from providers/amazon-bedrock/models/, even though the other Nova generation-1 models (nova-lite, nova-micro, nova-pro) are present there.

The Kilo provider already has a nova-premier entry, but the amazon-bedrock provider is the one consumed by downstream tooling (e.g. langchain-aws runs a daily refresh from models.dev and uses the amazon-bedrock provider).

Impact

Tools that derive LLM model metadata from the amazon-bedrock provider will not emit a ModelProfile for nova-premier. For example, langchain-aws runs a daily automated refresh from models.dev — without an entry here, downstream consumers fall back to conservative hardcoded token limits rather than the model's actual 1M-token context window.

Start with providers/amazon-bedrock/models/amazon.nova-pro-v1:0.toml and compare it with the AWS Bedrock model-card and pricing links in the issue. Add the missing amazon.nova-premier-v1:0 metadata entry, including verified pricing, limits, modalities, and capabilities; done means the amazon-bedrock provider exposes the model with the specified values.
