/**
 * Regression test for issue #2546: Grok CLI (xAI) token refresh not used,
 * session dies 40-45 min after login.
 *
 * Root cause: grok-cli mapTokens stored `expiresIn` but never `expiresAt`.
 * shouldRefreshCredentials() only reads expiresAt/tokenExpiresAt, so the
 * proactive refresh path never fired and only the reactive 401 path could
 * refresh — causing intermittent "token expired" failures.
 *
 * This test exercises the proactive-refresh decision path for grok-cli with
 * an absolute expiresAt. (The mapTokens unit portion cannot run in this
 * checkout because src/lib/oauth/providers.js self-imports the bare
 * "open-sse/index.js" specifier which vitest here does not resolve — a
 * pre-existing harness gap unrelated to this fix.)
