feat(google-vertex/google/alphafold3-request): add new models [bot]

[models-bot]

Auto-generated by model-addition-agent for google-vertex/google/alphafold3-request.

Note

Low Risk
Metadata-only addition with no runtime or routing logic changes; risk is limited to catalog accuracy if the model id or mode is wrong.

Overview
Registers google/alphafold3-request on Google Vertex by adding a new provider entry with mode: unknown and the model id google/alphafold3-request.

This is a minimal model-addition-agent stub (no provisioning, status, sources, or supportedModes yet), matching the pattern used for other newly discovered Vertex models before metadata is filled in.
