Moves the backing-track cluster — AudioFormatManager/reader/transport,
TimeSliceThread read-ahead, signalsmith-stretch state, lock-free speed
hand-off, BackingLeveler, playhead caches, and renderBackingBlockLocked —
verbatim into src/audio/engine/BackingPlayer.{h,cpp}.
Boundary per the plan (§2.4): control-thread lifecycle + non-blocking
getters live on the class; the RT mix POLICY (try-lock pattern, RMS
metering, volume fader, stream-submix capture) stays in the engine's output
callbacks via getLock()/readyLocked()/renderBlockLocked()/renderBuffer() —
both callbacks keep holding the try-lock through their stream publish, so
the render buffer is never read while prepare() can resize it. The volume
fader atomic and level meter stay engine-side.
Synthetic-reader unit tests deferred (JUCE-linked, same constraint as
StreamSink); covered by the backing play/seek/speed integration surface.
