 * Lightweight outbound internet connectivity check.

 * Probes a reliable public endpoint to determine if the current machine
 * has working outbound internet access. Used during provider-error handling
 * to distinguish "the provider's API is down" from "our internet is down" —
 * the two need different remediation (wait vs. fix local network).
 *
 * The result is cached for a short TTL so rapid successive checks don't
 * hammer the probe target.
 */
/**
 * Returns `true` when the probe endpoint responds successfully (any HTTP
 * status that isn't a server-side failure), `false` on network error or
 * timeout. The result is cached for `ttlMs` (default 30 s).
 *
 * Probing `1.1.1.1` (Cloudflare DNS) is intentional: it's a CDN-backed
 * static page served from virtually every PoP, so a failure almost certainly
 * means the local network is down rather than the probe target being
 * unreachable.
