"""Tests that known-noise hrefs don't show up as coverage gaps.

Each device-type registry folds in registry.capabilities.ignored.IGNORED so
that Bixby/voice/network/OTA housekeeping resources aren't reported as
unbound. This guards two things at once: that the ignored hrefs are
actually suppressed, and (via a plain import) that no ignored href
collides with a real capability declared elsewhere for the same family.
