/**
 * Tests for auth timeout bug fixes:
 *
 * Bug 1 (detect-region.ts): Region probe only sent Bearer auth — keys that
 *   only work with x-api-key would fail all probes, fall back to 'global',
 *   and every subsequent request would time out or 401.
 *
 * Bug 2 (refresh.ts): Token refresh had no timeout — a slow/unreachable auth
 *   server caused the CLI to hang indefinitely.
 *
 * Bug 3 (handler.ts): Timeout errors showed a generic "try --timeout" hint
 *   with no guidance about wrong-region or auth issues.
