gramps 8d23502220 fix(trax): the fader now actually changes the level — and the meter follows it 
Reported: pegging the TRAX fader changes nothing audible, the ladder never reaches red, and the
ladder does not scale with the fader.

Cause (two defects in the same setters):
- UserGain wrote the OUTPUT DEVICE's volume. NAudio's WaveOut ignores that, so the fader was inert.
- LocalGain (the desktop-mute follow) recomputed the sample-chain volume WITHOUT the user gain, so
  every duck/mute silently discarded whatever the creator had set.

Fix: one `EffectiveVolume(user, local)` = MusicVolume × user × local, applied to the sample chain by
both setters. The meter sits AFTER that stage, so the ladder now scales with the fader and can reach
the peak band on a loud track — exactly what pegging should look like. Max user gain is +6 dB, so
"pegged" means the file at unity, not a magic boost.

Guard: MusicLevelTests pins the arithmetic (default half, pegged double, mute multiplies to zero),
that the user gain survives the mute follow, and that nothing may drive the output device's volume
again — the no-op that made this invisible.

BackgroundEffects
TASK 51 blur 'heavy' fix: quadratic blur radius. BlurRadius(strength) = 1 + 5s^2, MaxBlurRadius 12 -> 6 downscaled px (~24 full px max). Default 0.5 is now radius 2 small px (was the old linear 6) - ~3x lighter perceived spread, matching the creator's real-camera finding. Range from the established tools: StreamFX defaults its Box blur Size to 5 and its author stops downscale-based blurs around 8px. One integration test pins the mapping (0 -> 1, 0.5 -> 2, 1 -> 6) and step-edge behaviour (light reaches 9px at default vs 26px at full); the existing slice-2 blur test passes unchanged. 419/419 pass.

CameraManager.cs
TASK 51 jitter fix: temporal mask smoothing. MaskSmoother blends each raw segmentation 0.75xnew + 0.25xprevious at the one CameraManager worker (state per CameraSession, not in the shared segmenter); null resets history, first frame passes through, input array never aliased, ping-pong buffers (no LOH alloc for a 147KB 256x144 mask). Creator's real-camera check: Remove was 'jittery' (per-frame independent segmentation). Weights from the OBS/Jitsi consensus. One integration test asserts the second frame keeps partial alpha (x=6 -> 58) where the raw mask cuts to 0. 416 pass / 2 known env flakes.
