feat(aws-bedrock-mantle/google.gemma-3-4b-it): add new models [bot]

[models-bot]

Auto-generated by model-addition-agent for aws-bedrock-mantle/google.gemma-3-4b-it.

---

Note

Low Risk
Config-only addition with no runtime or auth changes; pricing fields are region stubs only.

Overview
Adds a new aws-bedrock-mantle provider entry for google.gemma-3-4b-it, registering the model id and listing 14 AWS regions under costs.

The config sets mode: unknown, consistent with auto-generated mantle entries where routing/capability mode is not yet classified.

Cost entries missing all pricing data

High Severity

Every costs entry contains only a region key with no actual pricing fields (input_cost_per_token, output_cost_per_token, etc.). The existing aws-bedrock/google.gemma-3-4b-it.yaml includes per-region pricing for each entry. In the codebase, region-only cost entries without pricing data are exclusively used for deprecated/retired models (which also carry isDeprecated: true). This config represents a new, active model but will be emitted into the unified JSON with zero pricing information, likely causing downstream consumers to treat it as free or error out on missing cost data.

Mode set to unknown for active chat model

Medium Severity

The mode is set to unknown, but google.gemma-3-4b-it is an instruction-tuned chat model — the existing aws-bedrock equivalent uses mode: chat. In this repository, mode: unknown is consistently paired with isDeprecated: true on retired models. Using unknown on a new, active model means downstream consumers won't know how to interact with it correctly.
