/**
 * Live sign-in probe — is a harness's login actually usable right now?
 *
 * The status checks in {@link HarnessStatusService} only see whether a
 * credential is *stored*. For Claude Code that is not enough: an expired or
 * revoked login stays in the macOS keychain (and `claude auth status` keeps
 * saying `loggedIn: true`), so a machine whose every agent sits at
 * "Login expired · Please run /login" still looks logged in. The re-login
 * coordinator therefore confirms a suspected expiry with this probe before
 * telling the owner, and runs it now and then for harnesses in use so an
 * expiry is noticed even when no agent is running (the Air, 2026-09-30).
 *
 * - Claude Code: one tiny print-mode turn (`claude -p … --model haiku
 *   --no-session-persistence`) in a scratch directory, with the env agents
 *   get (a token Crewly stores is used, exactly as an agent would). Exit 0 →
 *   `logged_in`; output that matches a login-expiry rule → `logged_out`;
 *   anything else (network, rate limit, timeout) → `unknown`.
 * - Codex: `codex login status` (what the status check already asks).
 *
 * The probe never logs in or out and never prints a secret.
 *
