1.15.2

(fix): Fix OAuth (and inferred-auth) access tokens never being refreshed on expiry. The token was resolved once at client construction and baked into the RawClient’s static default headers, so every subsequent request kept sending the original (eventually stale) token until the client was reconstructed. The RawClient now receives the auth provider and resolves its auth_headers on every request, so the provider’s existing refresh logic runs before each call. Api-key/basic/ bearer/no-auth flows are unaffected (no provider is passed, so header resolution is a no-op).

1.15.1

(chore): Upgrade the generator to consume IR v67.
