Expose cancel-safe direct-I/O queues for reading rendered frames and
writing captured frames through the private broker endpoint.
Separate render and capture storage, publish format and state
generations, and preserve local loopback while no broker is bound.
Add a WaveRT adapter with render and capture endpoints backed by a
local ring buffer and shared presentation clock.
Advertise PCM formats through 192 kHz, eight channels, and packed
24-bit samples. Register LGAudio in the IDD solution and package it as
Looking Glass Audio.
