Subject: Initial tmix skeleton — model layer + basic UI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PulseModel: stable PulseDevice objects keyed by PA index, updated
in-place via postEvent reconciliation. No bulk rebuilds. Three signals:
deviceAdded, deviceRemoved (device changed handled per-device via
volumeChanged/muteChanged/nameChanged).

MixerWindow: four-tab layout (Output/Input/Playback/Recording), adds
and removes individual DeviceWidgets in response to model signals.

Builds and links cleanly against TQt3/TDE + libpulse.
