"""OpenCLI backend probing.

OpenCLI (github.com/jackwener/opencli) drives the user's real Chrome via a
browser-bridge extension + local daemon, reusing existing login sessions —
zero per-platform configuration, desktop-only (no headless).

Probing notes (verified live):
  - `opencli doctor` AUTO-STARTS the daemon — a side effect, so health
    checks must use `opencli daemon status` (pure query) instead.
  - Exit codes are always 0; status must be parsed from text output.
  - Extension connectivity is volatile (drops when Chrome restarts and
    reconnects on demand) — report it, but treat "installed + daemon
    reachable" as the stable signal.
