Function canonicalize_v2_model_provider_name 

pub fn canonicalize_v2_model_provider_name(name: &str) -> &str

Map a V2 model-provider family name (synonyms, regional variants, OAuth suffixes) to its V3 canonical family. Production configs are normalised at TOML load time by normalize_provider_type in zeroclaw-config/src/schema/v2.rs. This helper duplicates the same table at the runtime factory boundary so callers that bypass the schema migration (programmatic factory invocations, tests, the create_model_provider_with_url colon-URL legacy entry point) still resolve. Inputs that are already canonical or unknown pass through unchanged.
