apron-auth 0.2.0 can replace custom Google/GitHub identity fetch logic

apron-auth 0.2.0 introduces OAuthClient.fetch_identity with built-in handler inference for Google and GitHub based on provider endpoint hostnames (including manually-constructed provider configs targeting those hosts). This allows application code to remove direct /userinfo and /user API calls for those providers and map IdentityProfile fields (email, subject, username) into local metadata. Verified against the 0.1.0...0.2.0 changelog and compare output on 2026-05-05.

When upgrading to apron-auth >=0.2.0, replace custom Google/GitHub identity profile calls with OAuthClient.fetch_identity(access_token), and keep provider-specific fallbacks only for providers without built-in identity handlers.
