feat(aws-bedrock-mantle/anthropic.claude-fern-trn2-1024k): add new models [bot]

[models-bot]

Auto-generated by model-addition-agent for aws-bedrock-mantle/anthropic.claude-fern-trn2-1024k.

---

Note

Low Risk
Adds a new provider config file only; no runtime or auth changes, with placeholder mode and incomplete cost data.

Overview
Adds a new aws-bedrock-mantle provider entry for anthropic.claude-fern-trn2-1024k, auto-generated by the model-addition agent.

The YAML is a minimal stub: mode and supportedModes are set to unknown, and costs only lists us-east-2 without per-token pricing (unlike fully fleshed-out sibling model files).

Missing Anthropic Mantle path prefix

High Severity

This Anthropic Claude model omits extra_configuration.bedrock_mantle_adhoc_prefix: /anthropic. Every other anthropic.* model in this provider sets that prefix so the gateway injects /anthropic before /v1. Without it, inference is sent to the plain Mantle /v1 path instead of the Anthropic Messages API and fails.

Claude model marked mode unknown

Medium Severity

mode is unknown for anthropic.claude-fern-trn2-1024k. Sibling Claude models in this provider use mode: chat, and the gateway uses mode to decide how to expose and route a model. Leaving it unknown keeps this new Claude model from being treated as a chat model.
