rmnet_data1 on the OnePlus is the carrier's IMS/VoLTE network: it carries
IMS&MMTEL but neither INTERNET nor NOT_RESTRICTED, so binding needs
CONNECTIVITY_USE_RESTRICTED_NETWORKS - signature-level, unobtainable.
EPERM there is permanent and says nothing about any network's health, but
the constraint detector counted it, so a phone with VoLTE reported
'measurement blocked' on every run and every verdict came out
INCONCLUSIVE. Capabilities now decide: networks an app may never bind are
recorded as app_usable:false in networks[] and skipped, rather than
reported as something the run failed to do.
Also retires the 'while it tears down' wording, which was a guess that
turned out to be wrong - the refusal outlasts the VPN indefinitely, so
the text now names the VPN as the usual cause without asserting a
timeline it cannot know.
App version 0.2.4.
