// login_poll_test.go — httptest-backed coverage for login polling helpers
// (pollForAuthCompletion, pollForTierUpgrade, createCLISession, openBrowser,
// loadAnonymousTokens, runUpgrade). The mock API in testapi_test.go already
// handles /auth/cli + /auth/me; here we drive narrow scenarios (timeouts,
// network errors, malformed bodies, etc.) using bespoke httptest servers
