feat: add transient suppressor to audio pipeline

Browse Source 
Implements a per-sample transient suppressor in the noise gate AudioWorklet
that instantly cuts gain when a sudden loud peak (desk hit, mic bump) exceeds
the slow background RMS by a configurable threshold, then releases over a
short window. Exposes enable, sensitivity, and release controls in the audio
settings tab.
