"""``hermes doctor`` probes survive a bracketed-IPv6 NO_PROXY environment (#118159).

Clash Verge / mihomo write ``[::1]`` into NO_PROXY; httpx 0.28.1 turns that into an
unparseable ``all://*[::1]`` mount, so every probe's bare ``httpx.get()``/``httpx.Client()``
raised ``InvalidURL: Invalid port`` and the probe table misreported broken connectivity for
every provider. ``run_probes`` (the single entry the doctor uses for the whole table) sanitizes
the environment once before any worker builds a client.
