v0.3.3

Clarify: any USB cable, not just USB-C

CableProbe watches how the host reacts to a cable, not the plug, so a USB-A
implant cable (the original O.MG form factor) is fully in scope. Documentation
and --help now say "USB-C or USB-A, charge-only or data", with a note that
connector type does not matter (use a passive adapter if you need one).

The usbc_pd probe stays USB-C specific — it reads /sys/class/typec and skips
cleanly on a USB-A-only host.

Doc / help text only; no behaviour change. pipx upgrade cableprobe.
