AWS credential lookups now time out with a clearer error, and you can raise the timeout via an env var.
AWS credential-chain resolution — covering STS GetCallerIdentity, ListInferenceProfiles, and profile/SSO credential fetches — is now wrapped with a request timeout. On timeout, the error message tells users to raise CLAUDE_CODE_AWS_CHAIN_RESOLVE_TIMEOUT_MS, and a separate generic message covers other AWS timeouts.
